Notes
NOTES:Freezer bags are by far the best container.You can also freeze in rigid plastic freezer containers.You can freeze in mason jars.But I don’t recommend it.They break and are inconvenient in the freezer.Onions will remain good in the freezer for 6-8 months.After that the quality may start to diminish.
