🧾Ingredient Notes
- Blackberries-In the spring and summer, I always use fresh berries. However, when I make this in the winter, mainly for use as a breakfast syrup, I prefer frozen berries. They are sweeter than out-of-season fruit.
- White Sugar- Like all simple syrup recipes you can use any type of sweetener. Coconut sugar, honey, or agave are good substitutes. Try lavender sugar for a unique flavor.
- Water- I recommend filtering your water for a cleaner taste.
- Fresh Lemon Juice- This is optional but I think it makes the blackberry flavors more pronounced. Plus it increases the shelf life of the syrup.

💭 Blackberry Syrup Variations
- You can use this recipe with any berry you like or make a mixed berry syrup.
- Add a sprig of fresh thyme or rosemary to the syrup while it's simmering for an herb-infused flavor.
- Stir in a teaspoon of vanilla extract at the end, but skip the lemon.
- Swap out the lemon and use lime juice.
- Add a tablespoon of lavender sugar or rose water for a fragrant, floral taste.
- Mix in a few slices of fresh ginger or jalapeño pepper for a spicy twist.
🍲How to Make Blackberry Simple Syrup

Combine all the ingredients in a medium saucepan.

Use a wooden spoon or potato masher to break up the blackberries. This helps them release their juices.

Bring to a simmer and stir occasionally to help the sugar dissolve.

Puree in a high-speed blender, a food processor, or use an immersion blender.

Use a mesh strainer or cheesecloth to strain out the seeds and the solids.

Use warm or cool to room temperature before storing.
How to Thicken Simple Syrup
Frozen blackberries release more liquid, which can make your syrup thinner.
- Just simmer it a few extra minutes to reduce, or add a bit more sugar to help it thicken.
- More sugar for a richer, thicker syrup. It will be sweeter.
- Cornstarch slurry if you want less sweetness. Mix a small amount of cornstarch with water, whisk it in, and simmer until thickened.

👩🏻🍳 Expert Tip
Normally, simple syrup recipes use a 1:1 ratio of water and cane sugar. I prefer to reduce the sugar when making fruit syrups because of the additional sweetness the fruit adds. For a thicker syrup increase the sugar to 1 cup.
