Freezing Rinsed Blackberries

If you harvest blackberries and feel better with rinsing the berries before freezing them, it is best to quickly rinse them with cool water and place them directly onto sheets of paper towel after to help rid some of the extra water. If you do not, the berries will all clump together and be hard to use up.

Once you have dried off the extra water from berries, it is best to lay them out onto a cookie sheet lined with wax paper and toss them into the freezer to freeze. When the berries freeze, which takes about an hour, you can place the frozen berries into freezer bags and containers and freeze them for up to a year this way.

Again, after about a year, the berries will lose some of their juicy berry flavor and texture and can darken in color.

Freezing Sweetened Blackberries

To give blackberries a sweet flavor before freezing them so they will be sweeter in flavor when they defrost, simply harvest your blackberries, remove any stems and leaves, toss them into freezer containers and sprinkle some sugar over the top of them.

Next, place lids on the containers and gently give it a shake to combine the sugar and berries together well. After, freeze the berries and use them up within a year so they still have their sweet juicy flavor. However, freezing sweetened blackberries will cause them to be juicer and mushier in texture during the defrosting process.

How to Defrost Frozen Blackberries?

To defrost blackberries in raw form and rinsed form, simply take them from the freezer and place them into a berry bowl that has a paper towel lying underneath to catch any juices.

Berries take about 20 to 30-minutes to defrost. Once defrost you can eat them as is, toss them into yogurt or cereal or bake or cook with them the way you desire.
