Pink Sugar Bowl: Over Ripe Avocados? Don't throw them out! Most people do not realize you can freeze these whole food beauties! Just cut in half and remove the seed. Wrap in saran wrap (a vacuum sealer is the best option if you have one) then place into a freezer safe container or bag. I have never kept mine more than three months so not sure how long they will keep. When you are ready to use them thaw in the ice box overnight. Great for guacamole, homemade baby food, or chocolate mouse.
