I am making a cake for my SIL for his birthday but he is highly allergic to ALL things milk, even milk derivatives.
Any ideas what I could substitute the sour cream with that is not milk ANYTHING???
I tried searching this topic but got no results. I wish there was a turorial on how to search!!!
Maybe check Trader Joe's for a soy based sour cream or yogurt? Sorry, that's all I've got. Good luck!
