Jump to Recipe

Mocktails are really about finding a balance between tart and sweet, which this Blueberry Lemon Mocktail does an excellent job of doing. It comes together in 3 ingredients and is extremely customizable.

To get started, you’ll need the following ingredients:

  • 2 oz blueberry syrup (very easy to make)
  • 0.5-1 oz lemon juice (fresh)
  • Lemon or lime flavored sparkling water or seltzer

How to Make Blueberry Syrup

Simple syrup is, effectively, sugar dissolved into water over heat. Blueberry syrup means you’re adding blueberries to that equation, much like how you would make a compote.

To make blueberry syrup, you’ll need:

  • 1 cup of blueberries
  • 1 cup of granulated sugar
  • 3/4 cup of warm water (or 1 cup if you like a thinner syrup)
A cup of sugar, a bowl of blueberries, and a glass of water - all the ingredients for making blueberry syrup

Step 1: Add water, sugar, and blueberries to a saucepan and bring to a boil. Simmer on a low heat for about 10 minutes.

Step 2: Strain the blueberry syrup mixture by placing it in a fine mesh strainer and collecting the syrup in a bowl or mason jar. Use a heavy spoon to smush the berries and get as much of the syrup out as possible.

Step 3: Let the syrup cool before making your drinks (about 10-15 minutes).

For this recipe, you’re only going to use the syrup, but honestly, the sugar-smushed berries would go great over some pancakes or toast, so don’t let them go to waste!

How to Make a Blueberry Lemon Mocktail

Step 1: Gather your ingredients and equipment. You’ll need a lemon, your blueberry syrup, and a can or bottle of lemon or lime-flavored sparkling water. I used Topo Chico with Lime. You can use anything you like!

Step 2: In a cocktail shaker (use a mason jar with a lid if you don’t have one), add 2 oz (about 4 tbsp) of blueberry syrup, 0.5-1 oz (about 1-2 tbsp) of fresh lemon juice, and a few ice cubes. Put the shaker lid on and shake vigorously for about 15 seconds.

Step 3: Fill whatever glass you are using with ice (I used a small cocktail glass).

Step 4: Pour the blueberry lemon mixture into your glass.
