Today I got a recipe for homemade chocolate fondant...
The girl said that it tore in a few places, but she says that that's her fault...
The recipe is:
12 oz chocolate
4.5 oz liquid glucose
2 egg whites
28 oz powdered sugar
You melt the chocolate with the glucose, stir well and add 3 tablespoons of powdered sugar. Then you beat egg whites until stiff peaks and fold it in the chocolate... The rest is easy - you just knead and add the sugar in.

So? Is it a good idea to make this fondant?
Will it stay on the cake?
Did anyone have any experience with this?

Thanks in advance

I use cocoa, powdered sugar, marshmallows and corn syrup....the recipe is her on CC.
