One of the advantages of using Gelmix over other thickeners is that the displacement is very low, adding only 10 calories and 2.4g per serving. Gelmix only adds 2.4g per 3-4 fl. oz. at mildly-thick/nectar. 2.4g Gelmix per 4 ounces displaces the liquid about 2.5 ml, or a ratio of about 1 ml per 45 ml. This ratio is even less for slightly thick recipes, more commonly recommended for reflux, at 2.4g per 5-6 oz.
