There are a ton of great ideas for make-ahead, freeze-able meals on the board, which have encouraged me to freeze as much as I can. But I've noticed some ingredients don't do so well with that process. Potatoes for instance, but I don't know if that depends on what form they're in. In curries however, they always end up.... mushy and gross after being frozen. What other ingredients should I avoid if I plan on freezing?
