Fresh Mint Ice Cream with Salted Watermelon Granita

There’s something nostalgic about summer desserts—the kind that cools your whole body down after a long day in the sun. One summer, standing in my tiny kitchen with a bunch of mint that I didn’t want to waste and a watermelon I swore I’d finish, I experimented. What came out of that day was this refreshing, naturally vibrant treat: fresh mint ice cream layered with salted watermelon granita.

What makes this recipe stand out isn’t just its cooling contrast of creamy and icy textures or the sweet-and-salty balance—it’s how approachable it is for home cooks of any skill level. If you’ve never made ice cream before, don’t worry. If your only interaction with watermelon is slicing it into cubes, you’re in good company. This recipe breaks the process down into simple, manageable steps so you can create something that feels gourmet without requiring a culinary degree.

Besides being a beautiful, refreshing dessert, this combination also happens to be a healthier alternative to store-bought sweets. It uses fresh fruit, real herbs, and lets you control the sugar. Plus, the granita is dairy-free, making it friendly for guests with different dietary needs.

So whether you’re making this to cool down on a warm day, impress friends at a dinner party, or just try your hand at homemade desserts, you’re in for a treat. Let’s dive in.

Ingredients and Preparation

This recipe has two main components: the fresh mint ice cream and the salted watermelon granita. Each is simple on its own and comes together beautifully when served in layers.

Fresh Mint Ice Cream

Ingredients:

• 1 cup whole milk
• 2 cups loosely packed fresh mint leaves
• ¾ cup granulated sugar
• 2 cups heavy cream
• 5 egg yolks
• A pinch of salt

Optional substitutions:

• If fresh mint isn’t available, you can use 1–2 teaspoons of natural mint extract, but fresh is best for flavor and color.
• For a dairy-free version, try full-fat coconut milk in place of the cream and milk, but note the texture will be different.

Salted Watermelon Granita

Ingredients:

• 3 cups cubed seedless watermelon
• ⅓ cup granulated sugar
• 1 lemon, juiced
• 1 teaspoon flaked sea salt (or to taste)

Optional substitutions:

• Honey or agave can be used in place of granulated sugar for a natural sweetness.
• Lime juice can be used instead of lemon for a slightly sharper flavor.

Step-by-Step Instructions

Salted Watermelon Granita

1. Puree the fruit mixture: In a food processor or blender, combine the watermelon cubes, sugar, and lemon juice. Blend until completely smooth.
2. Freeze the mixture: Pour the purée into a shallow, freezer-safe dish like a metal or glass 9×13-inch pan. Place it flat in the freezer.
3. Scrape and break up the ice crystals: After 30 minutes, use a fork to scrape the mixture, breaking up any frozen edges and redistributing them toward the center. Continue scraping every 30 minutes for 3 to 4 hours, or until the mixture is fully frozen and fluffy like shaved ice.
4. Season before serving: Just before serving, sprinkle the top with flaked sea salt. Don’t skip this—it elevates the natural sweetness of the watermelon and brings the entire dish into balance.

Fresh Mint Ice Cream

1. Heat the base ingredients: In a medium saucepan, combine the milk, sugar, and 1 cup of the heavy cream. Warm over medium heat until it just begins to bubble around the edges—don’t let it boil.
2. Infuse with mint: Remove the pan from the heat. Stir in the fresh mint leaves. Cover the pan and let it steep for 1 to 2 hours. This step allows the mint to release its natural oils and flavor into the mixture.
3. Whisk egg yolks: In a separate bowl, whisk the egg yolks until smooth and slightly pale.
4. Temper the yolks: Reheat the mint-infused mixture slightly. Then slowly drizzle about a third of it into the egg yolks, whisking constantly. This step warms the yolks gradually so they don’t scramble.
5. Cook the custard: Pour the tempered yolk mixture back into the saucepan. Cook over medium-low heat, stirring constantly, until the mixture thickens slightly and coats the back of a spoon. This usually takes 5–8 minutes.
6. Strain and chill: Pour the custard through a fine mesh sieve into a bowl to remove the mint leaves and any cooked egg bits. Stir in the remaining 1 cup of cream and a pinch of salt. Let it cool to room temperature, then chill in the refrigerator for at least 4 hours, or until fully cold.
7. Churn: Once chilled, pour the mixture into your ice cream maker and churn according to the manufacturer’s instructions. This generally takes 20–25 minutes.
8. Freeze to firm up: For a firmer consistency, transfer the churned ice cream to a lidded container and freeze for 2–4 hours before serving.

Assembly

1. In individual serving bowls or glasses, layer scoops of watermelon granita and fresh mint ice cream.
2. For visual appeal and flavor balance, alternate layers so that every bite offers a bit of both.
3. Serve immediately or return to the freezer for a few minutes if you need time to prepare the rest of your meal.

Beginner Tips and Notes

• Don’t skip the scraping step in the granita: This is what gives granita its characteristic texture. If you forget to scrape, the mixture will freeze into a solid block. If that happens, just let it thaw slightly and start scraping again.
• Egg yolk tempering tip: Always whisk vigorously when adding hot liquid to egg yolks. If you’re unsure, pour the hot liquid slowly, and don’t stop whisking until it’s fully incorporated.
• No ice cream maker? You can pour the finished custard into a shallow container, freeze it, and stir every 30 minutes until it resembles soft serve. It won’t be as smooth, but still delicious.
• Prepping ahead: The granita can be made a day in advance and stored covered in the freezer. The ice cream can be made up to 3 days ahead. Just allow it to soften slightly at room temperature before scooping.
• Freshness matters: Use the ripest watermelon and brightest mint you can find. The better your base ingredients, the better the final dish.

Serving Suggestions

This dish shines on its own, but here are a few ways to enhance it:

• Pair with grilled chicken or beef skewers: The light, refreshing nature of the granita and ice cream makes it a perfect dessert after savory grilled dishes.
• Top with fresh berries or a drizzle of honey: This adds color, texture, and an extra layer of flavor.
• Serve in chilled glasses: Pop your serving bowls or glasses in the freezer for 10 minutes before layering the dessert. This keeps the granita from melting too quickly.
• Make it a float: Place a scoop of mint ice cream and a spoonful of granita in a glass and top with sparkling water or lemon-lime soda for a fizzy, refreshing treat.

Storage Tips:

• Keep the granita in a tightly sealed container to avoid freezer burn.
• The ice cream will stay good for up to a week in the freezer. Press a piece of parchment or wax paper onto the surface before sealing to prevent ice crystals.
• Avoid storing layered portions for too long, as the textures can blend. Assemble just before serving for the best experience.

Engagement Features

Making ice cream and granita from scratch might seem like a big step, but once you do it, you’ll wonder why you waited so long. The beauty of this recipe is in its simplicity, the way each component brings out the best in the other, and how forgiving it is if you need to make a few adjustments.

If you’re new to homemade desserts, this is a great starting point. There’s room to experiment with flavors, swap ingredients, or adjust sweetness to your taste. Try using basil instead of mint, or a mix of melon varieties for the granita. Each version will have its own character.
