Freshly picked berries are best enjoyed immediately, but freezing them is an effective way to prevent mold, and preserve their flavor and nutritional value for months.
To prepare berries for freezing, remove any stems or leaves, sort out unripe berries, rinse, and dry them. Put them in a flat layer on a tray, then freeze for a few hours.
Once frozen, remove the tray, scoop the frozen berries into freezer-safe containers or plastic bags, and return to the freezer. They'll be at their best for about 6-8 months.
Freezing changes the texture of berries, making them less ideal for fresh dishes. However, frozen berries are great for baking, cooking, or blending into various dishes and drinks.
