If anyone still cares, lol, I have solved the mystery of the pineapple in the Ohana bread pudding... was looking something up to ask someone else and realized why there is no pineapple in the recipe but it apparently is in there somehow anyway. The Ohana bread that they use to make it at Ohana has pineapple in it. So you will never find it explicitly mentioned in any recipes and if you make it at home with whatever bread you have lying around you will have no pineapple in it. But if you make it with ohana breakfast bread and bother to make that recipe first before making the pudding, THAT has pineapple in it.
Seriously went looking for this thread to share that revelation. Yes I need help lol. The OP is right and the rest of us are not crazy!
