About blackberries

Fun fact: blackberries aren’t true berries.


It’s true. In botany, a berry is a fruit with seeds and pulp formed from the ovary of a single flower. Blackberries are actually aggregate fruits that develop from several ovaries.

Substitutions and variations

  • use another fruit like raspberries or blueberries.
  • switch up the sweetener with brown sugar, Demerara sugar, or honey.
  • add in some orange or lemon juice to brighten the flavor.

About simple syrups

Simple syrups are a versatile and essential ingredient in many classic cocktail recipes. They are, um, simple to make and only limited by your imagination.

Simple syrups for cocktails are just sugar syrups, usually with equal amounts of sugar and water. This blackberry syrup is responsible for the flavor and that bright pink color in my blackberry vodka sour.

Recipe tips and tricks

To make the blackberry syrup, combine sugar and water in a small saucepan over low heat until the sugar dissolves. Add the berries, turn off the heat, and let it cool.

Unlike my blackberry swirl cream cheese brownies, there’s no need to fuss with a fine mesh strainer to remove the blackberry seeds. Just strain the blackberry syrup with a normal sieve into a glass jar. The berries you leave behind are a great little snack.

Store the simple syrup in the refrigerator until ready to use.

What to do with blackberry simple syrup

  • Use it in cocktails, like in this gimlet recipe. Or make a blackberry margarita with tequila, Cointreau, lime juice, and the blackberry simple syrup.
  • Add the blackberry syrup to lemonade or iced tea.
  • Stir it into yogurt and top with the leftover blackberries and homemade granola.

Recipe FAQs

How long does simple syrup last?

Stored in the refrigerator, it will last one to two weeks.

Can I freeze this blackberry syrup?

Maybe. You can try to freeze it in an ice cube tray, but it may only work if you have a deep freezer. That’s because adding sugar or other solutes to water lowers the freezing point.

How much blackberry syrup should I use in my cocktails?

The amount of syrup depends on the recipe. A good starting point is one-half to one ounce of syrup per cocktail, but you should adjust based on whether you like your cocktails sweet or dry.
