Stevia

Stevia is a sweetener made from steviol glycosides, which the FDA notes are natural constituents of the leaves of the stevia plant. Oregon State University Extension describes it as 200 to 400 times sweeter than sugar, sometimes with a licorice-like aftertaste.

Because only a tiny amount is needed, it contributes sweetness but none of the bulk, browning or moisture that sugar provides. Bakers therefore blend it with a bulking ingredient, or use it in recipes where sugar's structure matters less, such as sweetened drinks, custards, puddings and fruit fillings.

It is sold as a powder, liquid or a blended granular product made to measure like sugar.
