|An individual serving of rice just for you!|
I regularly make extra rice and freeze it, but I rarely think ahead to split it into smaller sizes. I usually take whatever amount is leftover and put in a Pyrex glass container with a rubber lid and throw it in the freezer. Whenever we need rice, I heat up the whole thing, which is sometimes way too much.
I don't know how easy they would be to get out of a metal muffin pan, but mine is silicone, so I can easily pop them out by pushing on the back.
