Clean berries. Pick out any green, mushy or moldy berries. Place berries in a strainer and rinse fully. Pat berries dry with a paper towel or lay out on a shallow pan to dry fully.
Refrigerate washed or thawed frozen berries for up to 5 days. Thawed frozen berries will also keep in your fridge for 5 days.
Freeze washed and fully dry berries in a freezer-safe container or re-sealable plastic bag. For the best quality, use berries within 8 to 12 months. Label the container or bag with the date and quantity using a marker and tape.
