Introduction

Food is a fundamental human need and an important component of our personal, family, and social well-being [1, 2]. It also serves as a means of communication through which we create, organize, and share meaning [3]. In Montanari's words, "food is culture," especially when it is produced, prepared, and eaten [4]. Since food and cuisine are symbolic representations of culture [5], they significantly contribute to personal and social identity [6,7,8,9]. Moreover, multi-culturally enriched dietary preferences and eating habits that are passed down from generation to generation are strongly related to the family environment and community [10] and are often resistant given their embedded nature in an individual's life [11].

The term "traditional" refers to the intergenerational transmission of food culture [12]. However, this definition is geographical, composition, preparation, and processing dependent [13,14,15]. Traditional foods have a specific cultural identity [14] and are the imprint of the past in the modern lives of every culture. They are considered to be  foods with beneficial properties because of their naturalness and inherited local preparation and processing [12, 15]. The unique ingredients and the utilization of very specific, traditional manufacturing methods have heightened interest in local and traditional foods in recent years [16,17,18,19].

European culture, identity, and culinary heritage are all shaped by traditional foods. Traditional food products have not only grown in popularity among consumers but also in policy discourse, particularly in the European Union. They are, therefore, immensely important throughout Europe [20]. In 2012, the European Commission updated the definition of the term "traditional" in foods, where it “means proven usage in the domestic market for a period that allows transmission between generations; this period is to be at least 30 years” [21]. Traditional and geographical indicators to food products, such as Protected Designation of Origin (PDO), Protected Geographical Indication (PGI), or Traditional Specialities Guaranteed (TSG), have been defined also by EU Regulation 2082/92 [22], as part of a food quality policy, maintaining and safeguarding their authenticity and origin [23].

In parallel, culinary tradition is classified as one of the core areas of intangible cultural heritage, along with social practices, rituals, and festivities [24]. There are several factors that determine the value of the culinary heritage, including commercialization, the influence of tourism, and globalization. The Mediterranean diet is certainly the best-known example, having been recognized by UNESCO [25] as an intangible cultural heritage of Cyprus, Croatia, Spain, Greece, Italy, Morocco, and Portugal. Moreover, the Mediterranean diet is as diverse as the societies that surround the Mediterranean region.

Greek cuisine, simple and basically traditional [26], is a component of the Mediterranean diet, as well as a part of Greece's lengthy history and the progeny of the Greek countryside [27]. Greek cuisine initially featured dishes from both mainland Greece and the Cyclades. Until the Treaty of Lausanne, the Ionian Islands, Thessaly, Epirus, Macedonia, Thrace, and the North Aegean Islands were gradually incorporated [27]. Following the displacement of the Greeks (Asia Minor, Pontus, Cappadocia) and the exchange of populations, under the Treaty of Lausanne (1923), their cuisine inspired local cuisine [28], particularly that of Macedonia (Fig. 1), a province of Northern Greece that was inhabited for centuries by Albanians, Bulgarians, Vlachs, Slavs, Sarakatsani, Armenians, Roma, Pomaks, and Sephardic Jews. Eventually, all these cuisines became part of the evolution of Greek cuisine [29].

The Pontic Greeks, whose homeland was proximate to the Black Sea Region of Turkey (Fig. 2), have one of the most fascinating and "non-Mediterranean" Greek regional cuisines [30]. Pontic Greek traditional cuisine is diverse and simplistic, incorporating traditions from mountainous and coastal regions, ancient Greece, nomadic regions, and influences from Russian, Turkish, Laz, Hemshin, and Armenian cuisines [31,32,33,34,35]. Greek Pontic cuisine consists primarily of grains and dairy products and its  foundation is formed by fermented milk products and a plethora of grilled dough dishes [36, 37].

Food and cuisine are part of the ethno-regional identity of Pontic Hellenism, which originated in Pontus (homeland) and was transferred to Greece (new place of settlement) [38]. For Pontic Greeks, food reinforces individual identity but also a sense of belonging to a group, a sense of communal solidarity and cohesion [39]. Since the Pontic Greek foodways are so important to their identity, they serve as the basis for academic and folkloric studies, and cookbooks are powerful tools. Furthermore, cookbooks can provide access  to local culture and shed light on the interaction of  local and national cultures [40].

The popularity of Greek traditional foods and local dishes has increased the number of cookbooks published in recent years. Local and ethnic cuisines are mentioned in some of these books, confirming the diversity of Greek culinary tradition. This research uses data from cookbooks and folklore publications to determine the most prevalent ingredients, foods, and dishes in Greek Pontic cuisine.

The Pontic region

The name "Pontic Greeks" comes from the term Pontus, after the Greek name Efxeinos Pontos, which means "hospitable sea," regarding the ancient Greek community that lived in northern Turkey for centuries [41]. The Ottomans referred to them as Rum, as a religious community and as an ethnic group [42]. In essence, the Pontus region can be seen as a modern analog of today’s Black Sea in Turkey.

The Pontus is fringed by the Pontic Alps, a large mountain range that stretches from east to west along the southern coastline of the Black Sea (Fig. 2) [43]. The coastline is fringed by rainforests that turn into large pastures in summer [44]. For the Pontic Greeks, the topography had a great impact on their history as it protected them from foreign invaders. For this reason, distinct economies and cultures naturally formed in this area [45,46,47]. The Pontus was mainly a productive and prosperous agricultural region. Giresun and Tirebolu produced a lot of hazelnuts, while oranges, potatoes, and onions were grown in Rize. Trebizond produced a lot of milk, butter, wheat, barley, corn, and potatoes. Besides food, Pontos was also rich in material resources. The mines of Gyumushkana, Tirebolu, and Koyulhisar were famous. Handicrafts and trade also grew [48].

Following ethnic and religious tension in both the Turkish and Greek regions, the authorities decided to perform a population exchange within these areas. Thousands of Turkish and Greek residents of Greece and Turkey who had lived there for hundreds of years were forced to migrate to another place. The process that turned minorities into refugees in both nations was codified when Turkey and Greece signed the Population Exchange Convention in Lausanne on January 30, 1923 [49]. However, Article 2 of the same Convention excluded the Muslims of Western Thrace (a Greek province) and the Greeks of Constantinople (Istanbul) from the exchange. Pontic Greeks settled mainly in Greece and the former Soviet Union after the Lausanne Treaty [50, 51]. After the population exchange, Greece had to deal with around 1.5 million refugees, most of whom were in a state of complete poverty [52, 53]. Their arrival in northern Greece (Macedonia and Thrace provinces) was extensively promoted by the Greek state. The largest mass migration waves of Pontic Greeks from the former Soviet Union took place in 1939, 1965, and 1988 [54]. The population of the Pontic Greeks is estimated to be 2.000.000 worldwide, with most of them now living in Greece [55]. Despite the fact that, in Greek historiography, population exchange is a symbol of national failure [56], the  Pontic Greeks have been particularly successful in preserving their ethnic identity [57].

Pontic Greek cuisine

The Greek Pontic traditional cuisine is characterized by simplicity and doricity, using simple ingredients, simple processing methods, and fast cooking [31, 37]. The diversity of this cuisine is the consequence of a historical confluence of geographical, social, and cultural elements. Culture is undoubtedly the most obvious factor in a community's or ethnic group's food preferences and choices, a fact that also applies to the Pontic Greeks and has deep historical roots [58, 59]. The environment, rituals and belief systems, human endeavors, and economic and political systems are also contributors. Furthermore, the cuisine of the various cohabiting ethnicities (Armenians, Turks, Russians, Hemshin, Laz) that coexisted in the Pontic region influenced Greek Pontic cuisine. Some of the common dishes found in these cuisines are tzirichta (a type of donut), malez (flour porridge), siron (a pre-baked filo-based pastry dish), and borscht (a hearty broth with meat and various vegetables).

Gastronomy in Pontus developed reverently following seasonality. However, the uncertainty created by the weather during the winter in Pontus forced the invention of ways of preservation and storage of food and raw materials (pickles, salted fish, pre-cooked pasta, cheeses, dried fruits, and vegetables) [60]. Vegetables, wheat, corn, and dairy products were the major product sources. Various methods were used to turn abundant summer milk into nutritious artisanal dairy products. The Pontic diet has religious roots. In the Orthodox Church, there are strict dietary restrictions and a long-term fast [39]. Along with wider acceptability and enforcement, fasting is a very significant cultural phenomenon [61].

Dairy products, especially those from lactic acid fermentation, led to the dietary and gastronomic "Pontian Galaxy" [62]. The most common are tyrin (cheese), oxygala (yoghurt), and tan (butter milk). Consumption of fermented dairy products is the key to longevity. The beneficial effect of probiotics on longevity was first disseminated by Metchnikoff in the early twentieth century [63], but was not picked up by the medical world until after the mid-1990s and is now a popular research topic [64]. Grains such as pligouri (bulgur), korkota (coarsely ground grains), fourniko alevri (baked corn flour) and barley flour cover a wide range of foods. Another culinary feature of the area of Pontus was the pre-baked pasta. Pre-baked pasta has the advantage of being cooked in a shorter amount of time than commercial pasta, while also being easily digestible and causing rapid satiety [65]. Soups, legumes, eggs, wild edible greens, fish, peas, and many pickled vegetables enrich the diet of Pontic Greeks [36, 37, 66,67,68]. Tables 1 and 2 provide a comprehensive reference to the food products and dishes of Greek Pontic cuisine, respectively.

Materials and methods

Cookbooks, culinary magazines, and folklore sources were consulted to determine the most common foods, ingredients, and dishes of Greek Pontic cuisine. Cookbooks were also chosen for research because, aside from their growing popularity [69, 70], they are among the most valuable resources for studying food, culture, and society [71]. Cookbooks are written records of oral heritage [72] that mirror social evolution and history [73, 74]. Likewise, they can contribute to the development of national and cultural identities [5, 40, 75], as well as the preservation of a link to one's ethnic heritage [76]. Nevertheless, recipes from extinct worlds, such as those of the Pontic Greeks, are highly valuable cultural elements [77].

As Greek traditional cuisine has emerged with a variety of local dishes and food products, the pace of cookbook publishing in Greece has skyrocketed. Some of these cookbooks focus on regional or ethnic cuisines, like the popular Cretan cuisine, which is associated with the Mediterranean diet. For reference, cookery books have been published on a variety of ethnic cuisines, such as the Vlachs, Laconians, and Pontic Greeks. Greek Pontic cuisine continues to be a very admired regional cuisine in Greece. This appears to be validated by the publication of six cookbooks on Pontic Greek cuisine in recent years. Besides that, the publication of two entire issues of the well-recognized and nationally published cooking magazine Gastronomos devoted to Greek Pontic cuisine, and the growing number of events dedicated to Greek Pontic cuisine by many local cultural associations, confirm the widespread popularity of the Greek Pontic cuisine. Also present in Northern Greece are a variety of small-scale food enterprises producing pasta, wheat, corn, and dairy products, all of which contribute to the dissemination of Greek Pontic cuisine. In addition, traditional recipes of Greek Pontic origin are becoming increasingly available online. Meanwhile, studies on Greek Pontic cuisine have been published recently [39, 78].

As for research materials, 6 cookbooks (Fig. 3) [32, 36, 66, 68, 79, 80], 2 cooking magazines (Fig. 4) [81, 82], 4 folklore books (Fig. 5) [83,84,85,86], and 4 folklore magazines (Fig. 6) [87,88,89,90] were selected (Table 3). Using the “Historical Dictionary of the Pontic Dialect” [91] was necessary for comprehending some names of Pontic foods and dishes, as well as their accurate representation in the text. Special emphasis is given to the collection of names of foods, ingredients, and dishes mentioned in the above publications. The current research recommends a thorough reading, as in folklore publications, the link between food, ingredients, and dishes is not so profound as in titles of articles or sections. One author is Greek of Pontic descent, so he is familiar with Pontic food culture. This enhances the reading and discovery of the constituents of Greek Pontic cuisine.

The food items, ingredients, and composite dishes were recorded on Apple’s Numbers spreadsheet software after being reviewed and documented extensively [92]. Initially, the names of foods, ingredients, and recipes were collected from all the above books, with the final number of entries being 2095. A second database was then made of the ingredients in the recipes from cookbooks and cooking magazines, with 6131 items recorded. The repeated mention of a food item in the text of an article or a book chapter was not counted. The database was meticulously created, and the recordings were double-checked. In the original listing, all Greek food names, ingredients, and dishes are transliterated into Latin. That way, the original name of the item or dish is preserved. The Latin transliteration is based on the ELOT 743:2001 standard, which relies on ISO 843:1999 [93]. In the second database, most ingredient names are translated into English, while some are transliterated from Greek into Latin.

We employed Voyant tools [94] suitable for text analysis [95] to depict common Pontic cuisines, ingredients, and recipes, providing data in a creative and reader-friendly way [96]. As a result of our research, we created word clouds that excluded words like "the," “and,” and "but" as well as common foods (water, salt, pepper, oregano, parsley, cinnamon, lemon, oil, and herbs), by putting the most frequently used words in the center and enlarging them to visualize variants. They display the frequency of various words in a text, but they may be used for much more than that. Although word clouds have limitations as an analytical tool, the academic community has embraced them [95, 97, 98].

Results

According to several publications, such as cookbooks, this study examines the most frequently occurring foods, ingredients, and dishes in Greek Pontic cuisine. The purpose of this introductory approach to the analysis of these publications was to highlight the fundamental elements of this simple yet intriguing cuisine. These books provide more than just recipes. They introduce the reader to the home-cooking process of Pontic Greeks.

Most cookbooks provide recipes based on the type of dish being prepared, whereas only the dishes of the cookbook Menu of Pontus present recipes and diverse products depending on seasonality and the annual cycle of feasts. Cooking recipes are frequently accompanied by intriguing folkloric elements that enhance the overall experience. Consequently, there is a projection of everyday life in the sphere of goods and dish preparation throughout the broader Pontus area. The diversity of Greek Pontic cuisine is quite well known, and variations of the dishes are frequently presented to demonstrate this.

In many cases, soups are made with water, milk, or yogurt, and in others, one type of grain or a combination of grains is used, as in the case of tanomenon sorva (cooking with decorticated wheat or a combination of decorticated wheat and barley). Further, chavitz, which is cooked with wheat flour in some places but with maize or roasted maize flour in others, is a dish that has been prepared in a variety of ways. This was motivated by disparities in what could and could not be cultivated in each location of Pontus. Grains like maize, in general, do not flourish at high altitudes [99]. As a result, the dishes were modified based on what the family had sourced.

What is noticeable is that most of the recipes combine dairy and cereals, with butter serving a prominent role. However, olive oil is frequently recommended as a substitute for butter. This could be attributable to the fact that olive oil is commonly accessible in every Greek household, or it might be for reasons related to the healthy characteristics of the Mediterranean diet. Of course, this may not be the best approach considering that the Greeks of Pontus are known for their "buttery" cuisine. On the other hand, it may be a way to enable contemporary Greeks, with or without Pontic origins, to become more familiar with Pontic cuisine.

In order to identify the frequency of occurrence of foods, ingredients, and dishes associated with Greek Pontic cuisine, we utilized Voyant tools to generate two word-clouds from our data analysis, as shown in Figs. 7 and 8, respectively. We examined the complete list of publications to produce the first word-cloud (Fig. 7), and we used only the cookbooks and culinary periodicals identified in the list to generate the second one (Fig. 8). At first glance, certain informed conclusions may be drawn about these word-clouds, but more research into the frequency of dishes or cuisines is required.

According to Fig. 7, beans, kale, bulgur, coarse cereals, soups, pilaf, chavitz, and foustoron are the foods and dishes with the highest frequency. Soups, bulgur, and beans are all common foods based on an analysis of the data collected from all publications. Table 4 shows the ten most popular dishes and their recipes. Soup was a popular dish among Pontic Greeks, so it is no surprise that it  appears so frequently in the data. As a result, tanomenon sorva is listed first in Table 4. Soups were eaten for breakfast, especially during the winter, because of their nutritious and satisfying characteristics. Tanomenon sorva is similar to Yayla Çorbası (Meadow soup) and Yoğurt/Yoğurtlu Çorba (Yoghurt soup) eaten in different parts of Turkey (Ağrı, Antalya, Artvin, Bolu, Çorum, Düzce, Erzurum, Giresun, Kayseri, Konya, Malatya, Muş,) [100]. It may be cooked with rice instead of coarsely ground wheat and topped with spearmint and thyme. Some of the other soups that were consumed included those made with snails, poultry, and beef, as well as lentils and beans with coarse cereals. The top three common dishes on this list are tanomenon sorva, chavitz, and foustoron (Fig. 9).

The top 3 common dishes of Pontic cuisine: (1) Soup with coarse grains, salty strained yogurt, and mint (Tanomenon Sorva), (2) A thick porridge meal with butter or milk cream and roasted corn flour (Chavitz), (3) An omelet with cow butter (Foustoron)

Table 5 includes the top 10 food products and food staples in descending order. Pre-baked pasta, dairy products, and foods that are produced through the fermentation process, like pickles, are among the most frequently encountered food products on. Anchovies, kale, and nettles are some of the most widely consumed staple foods. In Fig. 8, the word-cloud provides insight into the most common ingredients used in recipes in cookbooks and cooking magazines. Table 6 lists the twenty most popular ingredients in cookbooks and cooking magazines. Butter (13.43%), wheat flour (9.14%), eggs (6.31%), tomatoes (3.93%), milk (3.28%), bulgur (2.89%), corn flour (2.86%), and cheese (2.76%) are among the most frequently mentioned ingredients in cookbooks and cooking magazines. Unsurprisingly, butter tops the list, followed by various foods, including bulgur, which comes in sixth place. The fact that they are one of the fundamental elements of Pontic cuisine has been attested to here once again by the content of cookbooks and magazines used in this study.

Table 6 The twenty most used ingredients in cookbooks and cooking magazines

What quickly emerged through the visualization of those records is what foods and dishes the Greeks consumed in Pontus. The findings support the literature's assertion that fermented dairy products, grains, and vegetables play an essential role in Pontic cuisine. The list of the most popular dishes includes delicacies like chavitz, tanomenon sorva, and foustoron, which were very popular in Pontus, even among contemporary descendants of Pontic Greeks living in Greece. Thus, the results for the most common dishes are consistent with the contents of all the publications. The same is observed with the frequency of reference to staple foods and food products, such as kale, beans, potatoes, greens, butter, paskitan, and yoghurt.

In fact, every reader who reads these books will get a complete picture of the way of life of the Greeks of Pontus that has been transmitted from generation to generation. Also, one can find that Pontic dishes are easy to cook, as they only require the use of a few ingredients and easy ways of preparation. Obviously, they may not resemble the dishes prepared in Pontus a century ago or even earlier, but they are certainly able to satisfy the feeling of reviving these traditional dishes, at least for those of Pontic descent.

Discussion

Today's Greeks of Pontic heritage have mainly preserved aspects of their identity, such as dancing, dialect, music, customs, traditions, and diet. This is noteworthy as they did not have a geographical reference area, having lost all contact with their homeland. The Pontics' collective identity stems not only from their common past, but also from the community's common way of integration and relationship with the larger Greek society on an economic, cultural, and political level [101].

In both festive and everyday contexts, food is frequently associated with a sense of collective identity. Frequent gatherings of relatives are accompanied by meals and narratives that evoke memories, especially in older people, establishing food as a symbol of ethnic identity [39]. Kale with beans, various soups with yogurt and paskitan, dolmades, anchovies, pies, tzirichta, baklava, nuts, and other foods have been and are on the family's daily and festive table, at social events, on religious holidays, such as Christmas, and even at events of the local Pontian Cultural Associations. Apart from the second- and third-generation refugees, who have a more obvious and stronger link with the Pontic element, it appears that the fourth-generation refugees also prefer to consume certain Greek Pontic dishes, with the most popular being tanomenon sorva, pisia, borscht, and havitz [102]. Women, particularly mothers, grandmothers, and aunts, have a vital role in the transmission of tradition, memory, and history. On top of that, women are the primary decision-makers when it comes to deciding which traditional foods should be maintained and which newly available foods should be brought into their household [103]. They prepare the meals and cook the daily and festive foods, passing down practices and traditions. That seems to have unfolded in recent years [104]. Homemade food remains a vital symbol of the family, expressing family identity [105]. After all, identity is maintained through food in diaspora communities [106].

Food makes one feel at home in a new land [107]. The Pontic Greeks are feeling the same way as they defend the diversity of their cuisine in every way [39], regardless of the new trend toward healthier choices, which calls for using vegetable fats instead of butter, or the adoption of other eating habits because of globalization and multiculturalism or dietary acculturation [108], particularly in urban environments. Maybe that happened because their ancestors' gastronomic culture was left behind and remained with them symbolically rather than through a complete transplant of customary practices [109]. Although it is becoming increasingly popular in contemporary Greece, this regional cuisine continues to be largely absent from the official discourse, and there is a general lack of awareness of its distinctive characteristics [110]. This is supported, among other aspects, by the absence of social life for Pontic Cuisine [78] and the lessened interest in it among ethnologists in terms of ethnographic research [110].

The outcomes of this research show that the cookbooks and cookery magazines adhere to the philosophy of the traditional cuisine of the Greeks of Pontus, as established by literature and oral tradition. These publications can be recognized as elements in the promotion and transmission of Pontus' culinary tradition. Cookbooks are essential for disseminating traditional food knowledge [111]. Furthermore, cookbooks not only reinforce culinary traditions but also aid in the preservation of memories [112]. Since traditional food knowledge is a traditional practice of passing down food, recipes, cooking techniques, and expertise from generation to generation [113], these cookbooks are an excellent way of passing down this knowledge intergenerationally, as they are largely descended from Pontic Greek ancestors.

Conclusion

Greek Pontic cuisine is a unique and fascinating local cuisine found in the northern part of Greece. Culinary traditions have played an integral role in the preservation of Greek Pontic identity. One way of preserving and transmitting these culinary traditions is by oral tradition. This tradition can be passed down through cookbooks. These books, however, should not include a typical recipe record because just recording the ingredients and the preparation process is pointless. Interpreting recipes includes searching beyond the words and exploring whether recipes communicate moods, experiences, and emotions. After this, recipes gain symbolic meaning, placing food and culinary traditions at the foundation of the social formation of identity. Only then may cookbooks evoke the continuity and nostalgia of migrant families and their lost homelands. It is possible that cookbooks devoted to Pontic cuisine may be used to convey a genuine, traditional gastronomic culture to the Pontic Greeks in the future. An anthropological approach to books, on the other hand, could provide a definitive solution to the concerns above. Anyway, food culture is best explained via cookbooks, as recipes serve as a repository of cultural memory.
