🌟 Why You'll Love This Recipe

It only requires TWO ingredients. All you need is some fresh watermelon and some granulated sugar.

It tastes great. It's sweet and has the delicious flavor of fresh watermelon.

💭 What is Watermelon Syrup?

In most of my syrup recipes, the simple syrup is made by heating water, sugar, and some kind of flavoring (fruit, extract, etc.) on the stovetop. Not this syrup.

This syrup is a little different because it's made with only fresh, sweet watermelon and sugar. It's made by combining the watermelon and sugar in a container and allowing the fruit to macerate and give off all of its juices and flavor.

Once you strain out all the solids, you're left with a sweet, delicious, and brightly hued watermelon syrup that's great in so many beverages.

📝 Ingredients

This recipe only requires TWO ingredients!

👩🏻‍🍳 How to make Watermelon Syrup

  1. Start out by combining the watermelon and sugar in a zip top bag.
  2. Mix it all together, smashing the watermelon slightly. Stash it in the fridge for about 24 hours.
  3. This is what the watermelon will look like after about 24 hours. It's much juicier.
  4. Strain the contents of the bag through a fine mesh strainer. Discard the leftover watermelon chunks.
  5. You'll be left with a sweet, watermelon-colored syrup.

❓ FAQs

Can I use a different kind of sugar?

In theory, yes. But using a different kind of sugar (like brown sugar or turbinado) will change the flavor and color of your syrup. I also haven't tested this recipe with any sugar other than granulated sugar. So do this at your own risk.

Does simple syrup go bad?

Yes, it will eventually go bad. It should last about a week or two in the fridge if stored in an airtight container.

How long does simple syrup last?

This syrup should last about a week or two if stored in an airtight container in the fridge. You can prolong the shelf life a little bit by adding about half an ounce of vodka to the syrup.

Does simple syrup need to be refrigerated?

Yes, it needs to be refrigerated. Make sure to store it in the fridge in an airtight container.
