This study presents the results of a blinded test of the performance of five commercial thickeners. Experimental variables considered are brand of commercial thickener, type of liquid, desired thickness, and thickening time. Success of outcome is defined by a numerical rating scale comparing the consistency and taste to actual liquid samples. The findings suggest that no one commercial thickener consistently produces a desired consistency or was consistently superior regarding taste. Success in producing certain liquid consistencies and ``good taste'' varied according to brand, type of liquid, desired thickness, and thickening time used. It is suggested that specific recipes be developed for each brand and liquid to be thickened. Flavorings should be tested to enhance taste.
