how do i make fondant taste good?
If you are using Wilton fondant, then there is no fix for that. There are some commercial brands that taste good. Personal taste is a major factor here.
You can also make your own fondant. It tastes much, much better and is a lot less expensive. I have attached the link to my recipe.
There are variations in my cookbook as well. It's called "The Sugar Fix, The Recipes and Rantings of an Obsessive Compulsive Cook". The lick the spoon link will lead you right to it.
