Storing
Refrigerator: Keeps well for up to 3 days in an airtight container. Stir well before serving.
Freezer: Can keep for up to 2 months in an airtight container, however, freezing can change the texture. It's a good idea to freeze it in labeled containers, to keep track of the date, in serving sizes only as big as you'll need for one meal. Thaw overnight in the refrigerator, and stir very well before serving.
