The Key To Sugar-Free Frozen Custard: Sugar Substitutes

 

To make sugar-free frozen custard, sugar substitutes are often used. Johns Hopkins Medicine explains that there are three different categories of sugar substitutes. One category of sugar substitute (which can be over 200 times sweeter than white table sugar!) is artificial sweeteners such as aspartame and sucralose. Often not as sweet as artificial sweeteners, sugar alcohols like erythritol and xylitol are another sugar substitute that may be used. Finally, novel sweeteners, the third category, come from natural sources. Examples of this type of sweetener include stevia and monk fruit. As you explore the sugar-free frozen custard recipes below or on your own, you’ll find that these substitutes often appear in the ingredient lists.

 

However, while white table sugar may not be included in sugar-free recipes, there may be some naturally occurring sugars in the other ingredients, like the lactose in milk and other dairy products. If you are newer to exploring sugar-free frozen custard recipes or products with similar parameters in general, some explanation of the sugar-related terms that might show up in your search may be helpful. The American Heart Association, for example, explains the differences between “sugar free,” “reduced/less sugar,” and “no added sugar” indications on packages and nutrition labels. Note that there may be multiple terms used in a similar fashion, such as “sugarless” and a “trivial source of sugar” for sugar-free.
