Ingredients and substitutions

Ingredients on a countertop.
  • Lemon juice - I recommend using fresh squeezed lemon juice for best flavor. Lemon juice could be substituted with lime juice for a different flavor (much like a mojito).
  • Simple syrup - I recommend adding a splash of simple syrup, honey, agave, or maple syrup to this mocktail. The sweetness can easily be adjusted to suit your tastes.
  • Fresh mint - A must for this recipe. Fresh mint adds a bright, cooling flavor. It's a great way to use up some of that garden mint over the summer!
  • Lemon - You'll need at least one lemon round for this recipe. I like to add an extra lemon round as a garnish just before serving.
  • Club soda - Adds a light, bubbly flavor to the drink. Club soda can be substituted with mineral water or sparkling water. For a sweeter drink, club soda could be substituted with lemon lime soda like Sprite.
  • Coconut water - Adds a light coconut flavor and a little sweetness.

How to make a lemon mint cooler

Making a lemon mint cooler in a highball glass.
  1. Add lemon juice and simple syrup to a highball glass.
  2. Add mint leaves and a lemon round then muddle until aromatic.
  3. Top with ice and then add coconut water and club soda.
  4. Stir gently to preserve the soda's fizz and serve immediately.

Tips and tricks

Use a highball glass - Use any highball glass around 8 to 12 ounces in size for your lemon mint coolers.

Muddle your ingredients - Add the simple syrup, mint, lemon juice, and lemon round to the glass and lightly muddle until aromatic. If you don't have a muddler, use the handle of a large wooden spoon (like I did in the photo above).

Stir gently - After adding your coconut water and club soda, stir gently until just combined.

Optional garnishes - Add an extra lemon round and mint leaf to the top of your cocktail before serving.

Frequently asked questions

How many lemons do I need for this recipe?

You'll need at least one large lemon for this recipe. One lemon contains two to three tablespoons of juice. For one mocktail, you'll need about two tablespoons (one ounce) of lemon juice, plus one lemon round.

How do I make simple syrup?

Simple syrup is a 1:1 ratio of water and granulated sugar that's mixed over heat until the sugar is fully melted. To make simple syrup for this recipe, add granulated sugar and water to a saucepan over medium heat and stir until sugar is melted. Simple syrup can also be prepared in the microwave using short bursts of heat. Allow simple syrup to cool before adding to your mocktail.

What can I use instead of simple syrup?

Simple syrup can be substituted with honey, maple syrup, or agave.

How can I make my mocktail sweeter?

Add as much simple syrup as needed to reach your desired sweetness. Club soda could also be substituted with a lemon lime soda, like Sprite, for a sweeter beverage.

How can I prep these to make ahead of time?

To prepare your ingredients ahead of time, slice a lemon into rounds, clean and dry your mint leaves, and juice a lemon or two (depending on how many mocktails you're making).
