Out of the top of my head - I think you could do a freezer to put ice cream in if it takes too much time to assemble. To refreeze? :) Or some other mechanic that punished you if your icecream is not in the freezer for too long?
Ooo, yes! Almost similar to putting something in an oven in a more traditional cooking game, but more optional. Or maybe getting multiple orders at once and being able to hold them in a freezer.
