Tips for better sugar swaps
-
Blends of two sweeteners (e.g. allulose + monk fruit) often taste the most like sugar.
-
Powdered erythritol dissolves better in frostings and no-bake desserts.
-
Skip maltitol: it raises blood sugar far more than other sugar alcohols.
-
If you have concerns about erythritol research, rotate in allulose, stevia or monk fruit extract.
