Ingredients
You need just a few things to make your own Blackberry Simple Syrup at home.
- Granulated sugar: This adds the sweetness to the recipe. You can make a 1:1 simple syrup (1 cup water, 1 cup sugar), or you can reduce the sugar and reduce the sweetness with a 2:1 simple syrup (2 cups water, 1 cup sugar).
- Fresh blackberries: These are the star of the show, so be generous when adding them to the recipe! I suggest using fresh berries, but this would also work with frozen berries.
See full recipe below for detailed directions.

How to Make Blackberry Simple Syrup
This Blackberry Simple Syrup comes together in just a few minutes.
Combine sugar and water in a small saucepan or skillet. I find a pan that gives you a larger surface area works best with the berries.
Add the blackberries and stir until the sugar dissolves.
Bring the mixture to a low boil, then reduce heat and simmer. Mash the berries with a wooden spoon while stirring occasionally.
Let the mixture cool, then strain the syrup into a bowl, discarding the seeds and pulp. Transfer the syrup to a jar or airtight container and store in the refrigerator.
Expert Cooking Tips
- Be generous with the berries! This is the flavor that you really want to capture in this Blackberry Simple Syrup, so err on the side of adding more, rather than fewer blackberries! It will give you more flavor.
- Mash the berries as they are simmering. The berries will start to break down naturally as they are cooking, but you can also mash them with a wooden spoon as you're stirring to get the most juice out of the berries.
- Let the syrup cool before straining. There is no need to work with it while it is hot!
- As you're straining, use a spoon to mash the berries against the mesh of the strainer. This will also help to get out as much juice as possible from the berries.
- Store the syrup in an airtight container in the refrigerator. This will keep for about one month.

Equipment
You'll need a small saucepan or skillet, a wooden spoon for crushing berries, and a strainer. Store the simple syrup in a glass jar or airtight container.
Storage
Refrigerator Storage: Once the simple syrup has cooled, store it in a jar or airtight container in the refrigerator for up to one month. This simple syrup has not gone through the canning process, so it is not shelf-stable.
If at any time you notice that the syrup seems cloudy, or suddenly there are "floaters" in it, it's time to discard and start fresh, as those are indications of mold.
