It's easy to make ice in a pressure cooker, much easier than making bread.
To make ice cubes in a pressure cooker, place one ice tray in the bottom of the pressure cooker. Add two inches of liquid nitrogen, cover, and wait for the pressure weight to stop moving.
Open cooker, remove ice cube tray, pop out ice cubes.
See? just two ingredients, time and temperature totally not critical.
