For my lunch with ham, I think I'd like to do a pineapple upside downcake. I usually only make it with apricot or peach or rhubard and use a nicer buttercake. But my crowd tomorrow will love pineapple. I've only made it in a round pan or skillet. I hate to do a bunch of them. I suppose I can get chunks of pineapple instead of rings and put anytype of yellow cake on top? or what do you suggest for about 25? really may be more like 28.
