Step 1
Place fresh blueberries into a strainer in your sink. Let them sit in the strainer for at least 10 minutes to allow most of the water to drain. Don't rinse your berries in water until you unfreeze them.
-
Step 2
Put the blueberries in an airtight container, and place it near the back of the freezer. Leave it there overnight.
-
Step 3
When you take the blueberries out of the freezer, place them in the plastic bags that are specific to your food sealer. Pat down the areas around the bag to remove any air that could cause drying or freezer burn.
-
Step 4
Seal the plastic bag using a food sealer vacuum, such as FoodSaver, Reynolds Handi Vac or the Tilia Advanced FoodSaver vacuum. If you don't have a vacuum sealer, you can place a straw in a plastic bag and suck out as much air as possible. Quickly zip the bag once most of the air is removed.
-
Step 5
With a black marker, label your bag with the date, and store the vacuum-sealed bag of blueberries in your freezer. Take the blueberries out the night before you want to use them, and place them in your refrigerator to thaw. Make sure to rinse the berries in cool running water.
