How to Make Watermelon Simple Syrup

Here’s how to make a watermelon simple syrup that’s sweet, fresh, and full of real fruit flavor.
 

1. Gather Your Ingredients

You only need three things to make watermelon simple syrup: fresh watermelon, granulated sugar, and water.
 
Use about four cups of cubed watermelon, one cup of sugar, and one cup of water.
 
If your watermelon is extra sweet, you can cut the sugar down slightly.
 

2. Blend and Strain the Watermelon

Blend the watermelon chunks until smooth, then pour the puree through a fine mesh strainer.
 
Press the pulp with a spoon to get all the juice out.
 
You should end up with about two cups of fresh watermelon juice for your watermelon simple syrup.
 

3. Simmer the Sugar and Water

In a small saucepan, combine the sugar and water over medium heat.
 
Stir until the sugar fully dissolves, then let it simmer for about two minutes.
 
This creates the simple syrup base for your watermelon simple syrup.
 

4. Add the Watermelon Juice

Turn the heat down to low and stir the watermelon juice into the syrup.
 
Let it warm through for two to three minutes, but don’t let it boil.
 
Boiling can dull the fresh flavor of your watermelon simple syrup.
 

5. Cool and Store

Remove the saucepan from the heat and let your watermelon simple syrup cool completely.
 
Pour it into a clean jar or bottle with a tight lid.
 
Your watermelon simple syrup will keep in the fridge for up to two weeks.
 

Tips and Variations for Watermelon Simple Syrup

A few small tweaks can take your watermelon simple syrup to the next level.
 

1. Add Herbs or Citrus

Toss in a few mint leaves or a strip of lime zest while the syrup simmers.
 
Strain them out before storing, and your watermelon simple syrup will have a lovely herbal twist.
 

2. Use Less Sugar for a Lighter Syrup

If you want a thinner watermelon simple syrup, use half a cup of sugar instead of a full cup.
 
Just keep in mind that less sugar means a shorter shelf life.
 

3. Strain Twice for Clear Syrup

For a crystal-clear watermelon simple syrup, strain the juice twice through a fine mesh strainer or cheesecloth.
 
It’s a small step that makes a big difference in presentation.
 

4. Freeze Extra Watermelon Juice

If you have leftover watermelon juice, freeze it in ice cube trays.
 
Later, you can thaw the cubes and turn them into a fresh batch of watermelon simple syrup.
 

So, How Do You Make Watermelon Simple Syrup?

You make watermelon simple syrup by blending fresh watermelon, straining the juice, and simmering it with a basic sugar and water syrup.
