Blackberry simple syrup is one of my favorite ingredients for the cocktails that I make. Simple syrup is a versatile ingredient that can be used in a variety of cocktails and mocktails. It’s easy to make! In this recipe, we’ll be using blackberries to create a sweet and fruity simple syrup that is perfect for adding to cocktails, lemonade, iced tea, and more.

Ingredients for Blackberry Simple Syrup:

1 cup of blackberries
1 cup of sugar
1.5 cups of water

Instructions for Blackberry Simple Syrup:

Rinse the blackberries and place them in a small saucepan.
Add the sugar and water to the saucepan and stir until the sugar has dissolved.
Turn the heat to medium-high and bring the mixture to a boil.
Reduce the heat to low and let the mixture simmer for about 10 minutes, or until the blackberries have broken down and the mixture has thickened slightly.
Remove the saucepan from the heat and let it cool for a few minutes.
Use a fine-mesh strainer to strain the mixture into a clean container, discarding the solids.
Let the simple syrup cool to room temperature and then transfer it to an airtight container.

How Long Do Blackberries Last?

Blackberries can last between two to three days in your refrigerator, after which they can start to rot and turn moldy. You can freeze blackberries and store them in the freezer so that you can access the fresh fruit year-round: Freezing blackberries can extend their shelf life up to nine months.

How to flash freeze blackberries:

1. Wash in cold water. Place the berries in a colander or strainer and rinse them with water. Alternatively, swish them around in a large bowl of cool water.

2. Use paper towels to dry. Lay your blackberries in a single layer on paper towels or a cloth kitchen towel. You should largely allow them to air-dry, but you can pat them dry with a paper towel to speed up the process.

3. Arrange on a baking sheet. Place the blackberries on a cookie sheet lined with parchment paper to prepare them for flash-freezing. Ensure that none of the berries are touching, or else they’ll clump together during the freezing process.

4. Flash freeze for three hours. Slide the baking tray into the freezer and leave it there for at least three hours. You can freeze it for longer, but the total time should not exceed twelve hours. This step, known as flash freezing, will prevent the individual berries from sticking to each other once in a freezer bag.

5. Transfer to freezer bags. Remove the baking tray from the freezer and store the frozen berries in thick plastic bags or a freezer-safe container for long-term storage. You can keep these frozen blackberries in the freezer for up to six months without freezer burn or notable flavor loss. If you mix the blackberries with one cup of sugar before freezing them, you can extend their preservation time to nine months in the freezer.
