The idea here is to basically re-steam it, that’s why it stays tasting fresh rather than like dry/hard day old rice that’s been in the fridge.
- take still warm rice
- sprinkle salt on a plastic wrap
- add rice, make it into a ball (other shapes won’t work), squeeze the air out
- portion them out to freeze for the week (or longer)
I nuke them for a minute or two (depending on if they’re defrosted or not, and depending on the power of the microwave- the one at work is a BEAST) and have what tastes like perfectly moist, fresh rice all week long!
