What’s in this cocktail?

There are only five ingredients in this fruity cocktail!

  • Blackberries: Ripe blackberries have a sweet flavour with slight tart notes. They have been said to taste like a mix of black grapes and raspberries.
  • Lemon Juice: The juice adds bright, zesty, and sour flavours. It wonderfully complements the sweet blackberries.
  • Simple syrup: It’s made with equal parts white sugar and water. You can purchase simple syrup or see the “Useful Tips” section of this post to see how to make it.
  • White Rum: The alcohol component of this cocktail. The subtle sweet notes of white rum let the fruit be the forefront of this cocktail.
  • Ice cubes: Keeps the drink nice and cold.

Here are Some Useful Tips

  • When looking for blackberries, choose ripe ones that are plump (soft, not mushy, and rich blue-black all over). They will taste sweet.
    • Underripe blackberries tend to be a lot more tart and can be bitter.
  • To get more juice out of a lemon, roll a room temperature lemon on a flat surface to break down the citrus membranes before cutting in half. Use a citrus juicer to get the most juice out.
  • How to make simple syrup? In a saucepan, combine one-part white sugar with one-part water. Bring to a boil and stir to completely dissolve the sugar. Remove from heat and let it cool. The resulting mixture should clear (not cloudy).
    • To keep for up to one month, pour the simple syrup into a sterilized container and store in the refrigerator.
  • Why not add sugar instead of simple syrup? Sugar may not fully dissolve into the drink, which results in sugar crystals settling onto the bottom of glass making the cocktail uneven in flavour and texture.
  • Switch it up with a different liquor such as bourbon, vodka, or gin if you like.
    • Just note that changes in alcohol will change the overall flavour profile of the drink, especially if the liquor is strong.

  • Quick and easy to prepare: This recipe uses a few ingredients and comes together in minutes.
  • Adaptable: Add more or less alcohol according to your personal tastes. Switch out the rum with gin or bourbon too.
  • Scalable: This recipe makes one (generous) serving, but can easily be doubled (or more) to make many drinks to serve a small group.

  • ½ cup (10-12) fresh blackberries

  • 1½ oz. white rum

    2. Add the rum and three ice cubes to the cocktail shaker. Tightly seal the lid onto the cocktail shaker and shake vigorously for 45-60 seconds.
    3. Strain the blackberry cocktail into a double old-fashioned glass. Top with additional ice. Garnish with a lemon slice and straw if you like. Serve immediately.


*To make simple syrup: In a medium saucepan, add one-part sugar with one-part water. Then bring the water to a boil, stirring, until the sugar is dissolved. The mixture should be completely clear (not cloudy). Let the simple syrup cool before using in cocktails.

1/4 cup simple syrup would be very sweet for my palate, so I only used 1/2 ounce. Delicious and refreshing!

This cocktail is AMAZING!! After shaking in the shaker, I didn’t strain it...I love the little bits of blackberry in each sip. I also substituted Absolute Juice Strawberry Vodka and it was delicious!!!

I very much enjoyed this cocktail, switching up the rum with bourbon and adding a splash of club soda to cut the sweetness a bit.
