Many people complain that fondant does not taste that great. Here is a great alternative that I have found that you can make at home. I have not tried it myself but its surely cheaper than the buckets of Satin Ice I purchase.
1/4 cup vegetable shortening (Crisco)
1 pound of white mini marshmallows
1 teaspoon clear vanilla flavor
1 teaspoon butter flavor
2 tablespoons water
2 pounds powdered sugar
The video that follows is also very informative. It’s very abbreviated but what I think she did is melt the marshmallows shortening vanilla and water and added the wet ingredients to the powdered sugar.
