On a hot summer day, we’re all tempted to reach into the freezer for a frozen treat. Did a Homemade leg ice cream, Ice cream without whippingor a Fudgesiclean ice cold treat is the best way to cool down.

But when you want something a little lighter and super hydrating, but still a little sweeter than say flavored water or Frozen yogurt crustgranita is the perfect treat for you!

Granita is a semi-frozen dessert that is usually made with water, sugar and some kind of flavoring. The mixture is frozen until partially solid and then scraped with a fork to form flavored ice crystals that melt in your mouth—kind of like a fancy version of flavored ice.

This watermelon granita recipe replaces water with watermelon and uses a little honey and lime juice to dress up the flavors. It’s sweet, bright and extremely refreshing – the perfect summer dessert!

  • Fresh watermelon: You want to make sure your watermelon is REALLY ripe so your granita is super sweet. In fact, watermelon granitas are the perfect time to use up watermelon that’s been sitting in your fridge for a few days.
  • Fresh limes: The zest and fresh lime juice really make this simple dessert pop.
  • honey: The sweetness of your watermelon will determine how much sweetener you will need to add to the watermelon puree. I like to use honey, but maple syrup can be used to keep this dessert vegan-friendly.

How to make watermelon granita

The following tips are provided to help you achieve perfect results. You’ll find detailed instructions in the recipe card at the bottom of this post.

Blend watermelon

The base of the granita is made by blending watermelon with honey and lime juice until smooth. Easy!

Strain the watermelon

For best results, it’s a good idea to pour your watermelon mixture through a fine-mesh strainer straight into a shallow freezer-safe container. This will remove any seeds or chunks and keep the granita super smooth.

Scrape down the Granita during the freezing process

To get the ice like crystals that make granite granite, you need to remove the mixture from the freezer every 2 to 3 hours and use a fork to scrape the top layer of granite. Once you get to the less frozen parts, stop scraping and return to the freezer for at least another 2 hours. Repeat the process up to three times or until the granita is completely frozen.

Serve the granita

Although these watermelon granitas taste amazing on their own, I like to drizzle the granita with sugar flavored with fresh mint and lime zest. It really adds an element of WOW and freshness and couldn’t be easier to throw together and is as simple as mixing granulated sugar, ground mint and lime zest together.
