I'm preparing a cake for a family that needs it to be absolutely dairy and soy free. I have some experience in making dairy-free baked goods since my son was allergic to dairy and soy as a newborn and since I was nursing, I had to cut out all dairy and soy from my diet. When my birthday rolled around, I made myself some cupcakes and iced them with an icing prepared with dairy-free/soy-free margarine and icing sugar. They were not bad, if I do say so myself!
The margarine is made from cottonseed oil. Do you think I could put fondant over a cake that is covered in my margarine concoction? I don't think the icing will crust - do you think the fondant will slide off in that case?
Anyone have experience in preparing cakes for allergic people?
I do dairy free cakes exclusively. You should be able to put fondant over this frosting. Icing does not need to crust to be put under fondant. If you can get a dairy free, soy free margarine/shortening stick use that. I think Earth Balance has a stick that is dairy and soy free. The sticks have less water than the spreads and will work much better.
