Watermelon Granita

Watermelon Granita with Mint

This watermelon granita is a light and refreshing frozen dessert made with fresh watermelon, mint, and lime. Naturally sweet and icy, it’s an easy summer treat that doesn’t require an ice cream maker.

Inspired by classic Italian granita, this watermelon version is blended and frozen until fluffy and scoopable. Served on its own or topped with fresh berries, it’s an easy and effortless way to cool down on a hot summer day.

What Is Granita?

Granita is a traditional Italian frozen dessert made by freezing fruit juice or purée and scraping it as it freezes. Unlike sorbet, which is usually churned in an ice cream machine for a smooth texture, granita has a fluffy, icy consistency.

Ingredients for Watermelon Granita

You only need a handful of ingredients to make this refreshing frozen dessert:

• Watermelon – Use ripe, sweet seedless watermelon for the best flavor and texture.
• Fresh mint – Adds freshness that pairs naturally with watermelon.
• Lime juice – Brightens and balances the sweetness.
• Honey (or sweetener of choice) – Depending on the sweetness of your watermelon.

How to Make Watermelon Granita

Step 1: Combine honey and lime

Whisk together the honey and lime juice in a small bowl until fully combined and smooth.

Step 2: Blend

Add the watermelon and mint to a blender. Pour in the honey-lime mixture and blend until completely smooth.

Step 3: Strain

Strain the mixture through a fine mesh sieve set over a large bowl.  Press on the solids to extract the most juice. Discard leftover pulp.

Step 4: Freeze

Pour the mixture into a shallow baking dish and place in the freezer for about 1 hour, or until edges begin to freeze.

Step 5: Scrape

Use a fork to scrape the mixture, breaking it up into light, icy crystals. Return to the freezer. Continue scraping every 30–45 minutes until the mixture is fully frozen and fluffy.

Step 6: Serve

Scoop into chilled glasses or bowls and serve immediately.

Tips for the Best Watermelon Granita 💡

• Use very ripe watermelon for the sweetest flavor.
• Freeze in a shallow dish for faster, more even freezing.
• Scraping regularly creates lighter, fluffier ice crystals.
• Chill the watermelon beforehand for quicker freezing.
• Taste before freezing and adjust lime or sweetness as needed.

Variations for Watermelon Granita

• Make it citrusy – Swap lime for lemon.
• Try different herbs – Basil works beautifully in place of mint.
• Watermelon raspberry granita - For a berry variation, add about ½ cup fresh or frozen raspberries to the blender along with the watermelon before freezing to createsa slightly more tart, deeply colored granita with a beautiful pink hue.

Frequently Asked Questions

Why is my granita not fluffy?

This usually happens when it is not scraped frequently enough during freezing. Scraping every 30 to 45 minutes helps create a lighter, more delicate texture instead of large frozen chunks.

Can I make watermelon granita ahead of time?

Yes. You can freeze it fully in advance, then scrape again with a fork before serving to restore its fluffy texture.

Do I need to strain the watermelon juice?

It is optional. Straining removes pulp and creates a smoother granita.

Can I make the granita without added sweetener?

You can, but a small amount of honey helps improve the texture and prevents the granita from becoming too icy. If your watermelon is very ripe, you may only need a small amount, but including a little sweetener creates a softer result.
