Can You Freeze Mulberries?

Mulberries are a delicious fruit that can be used in jams, preservatives, baked goods, or simply eaten raw, fresh off the tree. Not only are mulberries delicious, but they are healthy too.

When Are Mulberries In Season?

Mulberries usually start to ripen on the trees between the middle of June through the end of August. Luckily, because mulberries are so easy to freeze, it is possible to keep your mulberries frozen throughout the year using the fruit in baked goods, preserves, or jams. But, if you recently planted mulberry trees, you may have to wait before you can harvest your first berries. Mulberry trees usually take about three years to mature before producing edible fruit for harvest. 

How To Freeze Mulberries

Freezing mulberries is a great way to keep your fresh harvest available throughout the entire year. Frozen mulberries can help preserve your berries later for baked goods or jams, and the freezing process is very straightforward. To freeze your mulberries, follow the steps below.

Step 1: Wash the Berries

Before packing your berries into the deep recesses of the freezer, you’ll want to make sure you give your mulberries a good wash. Not only does washing the berries remove dirt and debris, but it could eliminate dangerous bacteria, like E. coli or salmonella, that could be hiding in the nooks and crannies of the berries. To wash mulberries, simply run the fruit under cold water and let them drip dry for a few minutes in a colander.

Step 2: Baking Sheet

The best way to freeze mulberries is to put them in the freezer as s single layer. This method helps keep the shape of the berry intact, preserving the natural juices. Arrange the berries in a single layer spread out on a baking sheet or plate. Place the entire baking sheet or plate in the freezer to freeze for two hours or longer.

Step 3: Easy Storage

Once the single layer of berries is frozen, you can move the berries to a more accessible storage container that takes up less room in the freezer. You can choose formed containers or freezer bags. Make sure you find BPA-free containers to keep your berries safe and healthy. You’ll also want a container that forms an airtight seal to fight off freezer burn. 

How Long Can Berries Last in the Freezer?

When appropriately frozen and moved to airtight storage containers, mulberries can last in the freezer for up to six months and still retain their flavor. After six months, the berry will likely start to lose its flavor, degrading over time. Eating frozen berries past six months is not dangerous and doesn’t pose any immediate health concerns, but the taste will not be as complete as a freshly frozen berry.

Allow the berries to defrost naturally as they sit on the countertop. Ensure to unpack the berries from their container and place them on a plate or in a bowl to catch the water as the berries thaw.

These berries also have large amounts of resveratrol, which can help increase longevity.

Baking with mulberries outside their regular harvest season is possible if you freeze the berries while they are ripe. After harvesting the berries, be sure to wash and freeze the fruit in a single layer. Pack the berries into airtight containers and leave them in the freezer for up to six months.
