Really? You’re need to store them? Just eat them up!
Blueberries actually keep pretty well. Their small size keeps them from being too banged up in the harvesting, so there are fewer opportunities for damaged berries to spoil and ruin others in the basket. Store them in the refrigerator, loosely covered so they don’t lose much moisture and rinse them just before ready to use. To freeze them, the best advice is to spread them out on some kind of rimmed baking sheet (if you have room for such in your freezer) and then freeze. Once they’re frozen, put them into something for freezer storage. That way each berries is separate and you can remove just what you need when you’re ready to cook. Best advice is to use even the frozen berries within a few months. And you can always make jam!
