Dry-pack berries in poly bags or boxes can be found in the frozen food section of your supermarket. The frozen berries should feel loose, not clumped together.

Frozen blueberries are individually quick frozen so you can pull out a few or as many as needed.

Blueberries should be kept frozen and the unused portion returned to the freezer promptly. If not used immediately, cover and refrigerate thawed berries and use within three days.

Commercially frozen berries are washed before being frozen, so washing again is not necessary.

The secret to successful freezing is to use berries that are unwashed and completely dry before popping them into the freezer. Completely cover the blueberry containers with plastic wrap, store in an airtight, resealable plastic bag, or arrange dry berries in a single layer on a cookie sheet. When frozen, transfer berries to plastic bags or freezer containers.
