Ingredients
Equal parts fruit, sugar and water for this quick and easy Blackberry Simple Syrup.

See the recipe card below for the exact quantities of each ingredient.
- Blackberries: We use fresh fruit but frozen (slightly thawed) will work if it is not blackberry season.
- Granulated Sugar: White sugar adds sweetness to the tart berries, while also acts as a thickening agent for the syrup.
- Water: Helps to create the syrup.
For this recipe, you'll want to have on hand a small saucepan, measuring cups, spatula, fine-mesh trainer and an airtight mason jar.
Substitutions and Variations
With such minimal ingredients there is not a whole lot you can do to change up this recipe, but here are so helpful ideas.
- Sweetener: Use honey or maple syrup instead of granulated sugar for a more natural sweetness. You can use a brown sugar for a more molasses take on this recipe.
- Frozen Blackberries: If fresh blackberries aren’t in season, frozen blackberries work just as well—just let them thaw slightly before cooking. You may need to cook them down a little longer if there is some added moisture.
- Mix & Match: Combine with other berries like raspberries or blueberries for a mixed-berry syrup!
- Flavor Variety: Add a sprig of fresh thyme, rosemary, or a cinnamon stick while simmering for an herbal or spiced variation.
- Citrus Boost: A squeeze of fresh lemon or orange juice brightens up the flavor.
- Low-Sugar Version: Reduce the sugar and add a splash of vanilla extract for a slightly less sweet but still flavorful syrup. This may provide a shorter shelf life of the simple syrup.

Top Tips
- Letting the mixture maintain a rolling boil for about 15 minutes helps break down the berries, releasing their full flavor and natural juices.
- I like to strain it into a glass measuring cup then pour it into the glass jar while straining a second time.
- Double the sugar content to make a thick simple syrup, also known as rich syrup. This not only gives you an even more concentrated flavor, but it extends the shelf life to up to 6 months in the fridge.
- When you leave in the fridge it may start to crystallize. You can place the jar in a shallow bowl with, hot water to help break down the sugar.
- Make a thicker syrup by allowing it to boil down an additional 5-10 minutes.
