/ck/ - Food & Cooking

I don't know much about microwaves, so I'm just checking here to make sure that I know what they do. They just warm the food up, right? Like, if the food's already been cooked and has been put in the fridge, microwaving it won't do anything to make it safe to eat (e.g. killing bacteria), it'll just make it warmer and therefore nicer to eat, right?

Long story short, I'm asking because I've recently been tipping my pasta into a saucer of warm pasta source and just warming up the pasta that way. I'm just worried in case the usual method of microwave cooking actually has some medical benefit. In theory, would I be totally fine to just eat my pasta cold?
