Food Grade glycerin is a syrupy, odorless liquid used in baking because it adds sweetness to foods and helps retain moisture. When used in baking it is often used to soften icing and fondant. Glycerin helps to prevent sugar crystallization in candy. Using glycerin when making the fondant allows the final product to be looser, easier to apply and easier to work with. Its easy texture and sweet taste, add a special touch without changing the taste of your baked goods.
