I freeze my extra rice in single serving freezer bags. Than whenever I need rice, I just go to my freezer. It also is a huge time saver as whole grain rice takes forever to cook. These just need to be defrosted. I do the same thing with pasta. I always make extra and freeze it.
I usually use it in soups, or stir fry (with broth) with veggies.
I just did this with a batch of Jasmine rice that I made.
