How can I best preserve the freshness of blueberries by freezing them?
To best preserve the freshness of blueberries by freezing them, wash and dry the blueberries thoroughly, then spread them out on a baking sheet in a single layer and freeze them until they are firm. Once frozen, transfer the blueberries to an airtight container or freezer bag, removing as much air as possible before sealing. Store the blueberries in the freezer for up to six months for optimal freshness.
