June is blueberry-picking time in Missouri. There are several pick your own farms around where I live so anyone visiting me during these weeks can count on a trip to pick some.
Although some silly people - like one of my brothers who shall remain nameless to protect the guilty - worry about only picking what they can immediately eat, I don't believe there is such a thing as too many blueberries. What we don't eat fresh I freeze for enjoyment later, especially in the middle of winter.
Find the Right Container
I have several trays that fit my little door freezer so find one that works well with your freezer. A cookie sheet with raised sides will work, or even a pie or cake tin.
This is something that little hands can help you do so invite kids into the kitchen with you. Don't count the blueberries, some may inadvertently disappear in the process.
After washing and drying the blueberries, spread them into a single layer on the tray and place in freezer until frozen for several hours.
Once frozen, store in a freezer bag for easy individual berry retrieval later. Having the berries frozen like this makes it easier to grab a handful for cereal or to spread in a salad.
Works With Other Fruit
This applies to almost anything else you want to freeze. Once you get the system down, it will be easy to preserve extra fresh fruit for enjoyment during the off season.
