White cake with coconut....that one sounds familiar....by any chance is your bride asking for a wedding cake for 10 and sheetcakes for 120? If that sounds familiar has she asked you the same questions 10 times already and tried to get recipe info from you? I'm lovin' my wholesale customers more and more lately...brides are making me crazy
veg gel and agar can be used instead of gelatin.
florida crystals is vegan sugar, unbleached, no char, etc
you'd have to contact the maker of sweetex to verify it's not made with any animal producs
and try sub-ing tofu for yolks, but you'll need starch to thicken.
make sure the margerine is vegan..no casein or whey
watch out for red dye in food coloring...its in some blues, yellows..sorry I don't recall the brands.
trying to be helpful so sorry if I'm telling you stuff you already know.
hope this helps!
