I'm always careful not to reheat food more than once, particularly meat, fish, etc. So if, for instance, I make a tuna and pasta bake using tinned tuna, any leftovers get thrown away because the tuna was cooked before it was canned and then I cooked it again. Any more reheating could be dangerous. Couldn't it?
However, I've just been looking at recipes using ham (because I bought a pack of ham offcuts and want to make sure I use as much as possible once it's opened). A recipe for pea and ham soup had lots of comments saying that it freezes well. So the ham (already cooked when you buy it) is then reheated in the soup, then frozen, and then reheated again. That goes against all the advice on reheating food.
Am I being over cautious? Would other grans reheat leftover tuna pasta bake or reheat frozen pea and ham soup?
