When I have the space in my freezer, I make a batch of brown rice using 1/2 litre of dry rice. I do this when I'm going to be cooking rice anyways, since it doesn't take more effort or time to make more than I need for meal. Once the "leftover" rice is cool, we package it in 1/2 cup servings, wrapped in waxed paper. Then we fill all the little packets of rice into a freezer bag and stick it in the freezer. We usually freeze it on a tray, so the packets will be flat. After a few hours or the next day, we take the tray or baking sheet out of the freezer and leave the rice in the freezer.
When we want to use the frozen rice, it can be added to a stir fry, added to soup, or steamed or nuked (microwave heated) for use at the table.
May you live as long as you wish and love as long as you live.
