Throughout the year, we love baking with lots of blueberries. So during blueberry season when the markets put them on sale for $1 a pint, or when we're fortunate to go berry picking, we love to stock up and freeze them. The best method for freezing blueberries is to flash freeze them before placing them in your freezer bags.
After washing and drying the fresh blueberries, I spread them out on parchment lined baking sheets and place them in the freezer. You want to freeze them until they become as hard as marbles. Once thoroughly frozen, I place 2 cups of blueberries in each freezer bag so when we're ready to bake one of our favorite recipes, we can just take one bag out of the freezer and we're ready to go. (I use my FoodSaver Vacuum Sealer (love it!), but regular freezer bags work as well.)
When using frozen blueberries in your favorite recipes, do not let them thaw first, add them frozen. Your baked goods will taste just like you used fresh ones.
