Notes
Store: Refrigerate leftovers in an airtight container for up to 4-5 days. Cover and simmer on low heat for about 5 minutes or until warmed through.
Freeze: I do not like to freeze potatoes as they change color and texture but some people don't mind. Freeze in an airtight container with room for expansion for up to 3 months.
