So, I’ve been experimenting with some low-cal cake recipes for pesach. Bottom line, they dont work. now I know blah blah blah about food science and all that, but what I have been doing is replacing the oil with applesauce and only using one or two yolks with the rest as whites only. Sugar is now sorbitol. Problem is the cakes look fine in the oven but they sag when they cool. Any ideas or recipes?
