What is Blackberry Simple Syrup?

Blackberry simple syrup is a delicious syrup made by heating water, sugar, and blackberries until the sugar is dissolved and the blackberries have softened.

It uses the same basic formula as a regular simple syrup in a ratio of equal parts water and sugar, but it has the addition of plump, juicy blackberries, which gives it a deep purple colour and delicious berry flavour.

Blackberry simple syrup can sweeten cocktails, such as a refreshing Blackberry Bourbon Smash, mocktails or it can be drizzled on ice cream, desserts, pancakes and waffles.

This sweet, delicious syrup takes just 10 minutes to prepare, plus cooling time, and a bottle will keep in the refrigerator for about two weeks.

The syrup can be made using fresh or frozen blackberries, so you can make it any time of year, even if berries are not in season.

Pour it into a pretty bottle to make it a great hostess gift or addition to a cocktail-themed gift basket.

Ingredients

For a full list of ingredients and measurements, see the printable recipe card at the bottom of this post.

There are only three ingredients you need to make this delicious syrup.

  • Water
  • Granulated sugar
  • Blackberries

This syrup uses regular, granulated sugar. The sugar adds sweetness, thickens the syrup, and helps preserve it so you can store it in the refrigerator longer.

You can use fresh or frozen blackberries for this recipe. This means that even if blackberries aren’t in season, you can make it at any time of year.

If your blackberries are super sweet and you prefer a bit of tartness, add a few teaspoons of lemon juice to help balance the flavour.

A measuring cup of water, a bowl of sugar and a bowl of fresh blackberries.

Step by Step Instructions

Blackberry simple syrup can be made with just a few simple steps.

One – Place the sugar, water, and blackberries in a medium-sized pot.

Two – Stir and mash the berries with a spoon while heating the mixture over medium heat until the sugar is fully dissolved and the blackberries are softened.

Then remove the pot from the heat. Allow the syrup to cool while remaining in the pot.

Pro-Tip: The longer you simmer the syrup, the thicker and more concentrated and thicker it will become. For cocktails, it isn’t necessary to simmer it any longer than it takes to dissolve the sugar, but if you want to use it on desserts or waffles, you may want to allow it to reduce a bit more.

Three – Strain the syrup through a fine mesh strainer. Press the berries to release the remaining juice.

Four – Pour the strained blackberry syrup into a mason jar or bottle and store it in the refrigerator for up to two weeks.
