I am making a vegan birthday layer cake for a friend with the following dietary restrictions: no dairy, no eggs, no soy, no peanuts. I do need to grease and flour cake pans, but I can't find any information on what I can use to grease the pans with. Butter, margarine, and shortening are out of the question. I have used oil before, but that was not good. Alternatively, I guess if anyone knows of a brand of margarine or shortening that doesn't use soybean oil, that would work too. Any other suggestions? Thanks!
