🧾 Ingredients
- Water – If possible, use filtered or distilled water for purest tasting homemade simple syrup.
- Blackberries – Select firm, plump, fresh raspberries that are deep purple, almost black for the best tasting juice. Feel free to use frozen blackberries if blackberries aren’t in season.
- Sugar – The fine granules in granulated sugar, cane sugar, and caster sugar dissolve quickly to create a thick syrup. You can also use brown sugar. The added molasses and larger sugar granules will slow down dissolving and change the flavor profile of the syrup.
👉 Recommended Tools: For this simple homemade syrup, you’ll need a small saucepan and a sterilized glass jar or bottle for storage. You’ll also need a fine-mesh sieve to strain the blackberries.

🥣 How to make (step-by-step photos)
1️⃣ Step One: Dissolve sugar
Combine water, blackberries, and sugar in a small saucepan and heat over medium-high heat until the water begins to boil (about 5 minutes). Then, reduce the heat, and simmer until the sugar dissolves, and the blackberries break down and release their juices (about 5 more minutes).
2️⃣ Step Two: Press blackberries
Once the syrup thickens, strain it through a fine mesh sieve to remove the pulp and reserve the juices. To extract even more juice and flavor, use a cocktail muddler to press the pulp and then strain it. Finally, combine the extra juice with the syrup.
3️⃣ Step Three: Cool and store
After cooling, pour the syrup into a glass storage jar or bottle and keep it in the refrigerator for up to 2 weeks. To freeze, pour the simple syrup into ice cube trays and freeze, then store the frozen cubes in a freezer-friendly bag for up to 6 months.

🌿 Variations
- Keto-friendly syrup – For sugar-free blackberry syrup, replace sugar with an allulose granulated sweetener, monk fruit sweetener, or erythritol. Add 1/8th teaspoon of xantham gum to the mixture to help it thicken. Check out this keto simple syrup guide for more info.
- Infuse with fresh herbs – Simmer sprigs of fresh mint, basil, rosemary, or thyme with your blackberry syrup to add another flavor element.
- Extracts & dessert spices – Infuse your blackberry juice with a teaspoon of vanilla, almond, or lemon extract. Or add a dash of star anise, cinnamon, or nutmeg for a touch of warming flavor.

❔ FAQs
Yes. However, there’s a big difference between the flavor of fresh and artificial blackberry flavoring, so be sure to use natural blackberry extract. For every cup of simple syrup made with a 1:1 sugar to water ratio, add 1 teaspoon of blackberry extract, and then more to taste.
While homemade simple syrup infusions are recommended, brands like “Monin” and “Torani” are good brand name alternatives.
Sure! And there’s no need to thaw them first. You’ll just need to simmer frozen berries for another minute or two before they start to burst and get nice and juicy.
