4cupsfresh blueberries or strawberries, blackberries, or raspberries. Freeze as many berries as will fit on your sheet pan.
Instructions
Wash the berries and pick out any moldy or rotten berries. Dry the berries thoroughly on a clean towel.
Once fully dry, spread the berries on a sheet pan/cookie sheet. I like to line my sheet pan with parchment paper to keep the berries from sticking to the pan once frozen. The berries should be in a single layer. Don't overcrowd the pan.
Place the sheet pan in the freezer and freeze for about an hour (time will vary depending on amount and size of berries, may take anywhere from 30 minutes-3 hours). This method is known as "flash freezing."
Once the berries are completely frozen, spoon or dump the berries into an airtight container: a plastic freezer bag, silicone bag, or tempered glass container. If using a bag, remove extra air from the bag before sealing--this will prevent freezer burn issues.
How many blueberries can you freeze at one time? I find that about 4 cups of berries will fit in a single layer on a large sheet pan. This is why I suggest "4 cups" in the how-to above. But you can freeze any amount of berries desired. If you have a lot of berries, you'll need to freeze the berries in batches or use multiple sheet pans (if they'll fit in your freezer).
