Cool question. Iโd imagine the easiest way I can at least think of is spraying it with liquid nitrogen. The challenge will be to get the nitrogen back in the bottle and keep it liquid in the meantime.
I think that'd shake out to being an air conditioner with nitrogen as the "air." You'd lose some nitrogen every use, but nitrogen is cheap.
The problem is your piece of pizza would become as brittle and sharp as ice, and likely to injure you if you handled it.
You can dump energy into something by blasting photons at it, because photons carry energy. You can't do the reverse because you'd need to use particles with negative energy. Either that, or you'd need to suck photons out of the food, but it doesn't work that way; things radiate photons at a specific frequency and intensity (called blackbody radiation) depending on how hot they are, and you can't make them emit more energy except by getting them hotter.
yeah, not only microwave but heater in general... but reversed, i asked myself that question for a long time, i mean we pump an electricity into the wire and we get heat, why not reverse? why we can "magically" get heat from electrons but to get something cold we need to pump the heat elsewhere, like microwave basically make atoms vibrate generating heat, would be cool to be able to generate some field that makes atoms stop
It is called liquid nitrogen and it is too expensive to store.
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.
Flash freezing things is a thing.
