You would need to find a way to make food spontaneously emit microwaves so it loses energy and cools off. That probably involves altering the strength of one of the nuclear forces or something.

Liquid nitrogen bath, works opposite of a microwave, freezes it from outside and towards the middle.

There is a drink chiller that chills drinks in about a minute. You could use the same idea for other things.

You should try to build a chamber that sprays liquid nitrogen or other cryogenic liquids at the food.

Idk, good luck.

What I would like to know is if we will ever have microwaves that stop the spinning plate in the same place that they started. It's XXI century, I want to take out my cup as easily as I've put it in.

This was a b plot on the Bam Margera movie haggard.

Falcone wants his royalties

some kinds of fire extinguisher could accomplish this. bit expensive though.

In beer brewing there's a point where you want to cool your beer down as quickly as possible.
A chiller is dropped into the just cooked wort. (wort is the beer before fermentation).
It goes from steaming hot to room temperature very quickly.
It's just a spiral pipe that you run cold water through.
Sounds like you need something like that for a potato.

Furze did it... kinda

That's an air conditioner. Or a fridge.

You just need to adjust the output and input sizes. Do to like... physics. It is easier to add heat to a system than to remove it.
