The first time I tasted mint ice cream with watermelon granita, I was sitting on my porch at sunset, fanning myself with a magazine and wondering why I’d never thought to put these two summer staples together. The cold hit my tongue in layers—creamy, herbal, then suddenly bright and icy, like biting into a frozen garden.
My grandmother grew mint in a cracked terracotta pot that she never remembered to water, yet it thrived out of spite. She’d tear leaves into lemonade, but never ice cream. I think she would have loved this—the way the granita’s crunch gives way to silk, the way both flavors taste like August.
I make this when the watermelon on my counter starts to look lonely and the mint in my garden threatens to take over the yard. It’s become my answer to too-hot afternoons. If you’re new to frozen desserts, my kiwi sorbet was where I started learning how fruit transforms in the freezer.
What You Need to Make This Recipe
The mint matters more than you’d think—I use fresh spearmint, not peppermint, because it carries that cool sweetness without the medicinal edge. For the granita, you want watermelon that’s almost overripe, the kind that smells like candy when you cut it; the sugar concentrates as it freezes, so starting with bland fruit means icy disappointment. Heavy cream and whole milk form the ice cream base—skimp here and you’ll lose that luxurious mouthfeel that makes the granita’s texture so dramatic by comparison. I learned about balancing fruit and dairy from experimenting with cherry limeade sorbet, where the acid needs taming.
How to Make Mint Ice Cream with Watermelon Granita
I start with the granita because it needs time to crystallize. The watermelon gets blitzed with a touch of sugar and lime, then poured into a shallow pan. Every thirty minutes, I drag a fork through the freezing edges, breaking up the crystals until the whole pan looks like crushed pink gemstones. The sound of that fork scraping against metal becomes the rhythm of my afternoon.
While the granita works, I steep mint leaves in warm cream until the kitchen smells like I’ve walked into a garden at dawn. The leaves turn almost black, surrendering everything. I strain them out, whisk in sugar until it dissolves completely, then chill the base until it’s cold enough to hurt my fingertips.
The Ninja Creami transforms that chilled liquid into something that holds a scoop, dense and slow-melting. I run it through the Ice Cream cycle twice, because mint needs that extra spin to get truly smooth. Then comes the layering—ice cream first, a crater in the center, granita spooned in like a secret. My watermelon sorbet taught me how this machine handles fruit, but the dairy base behaves differently, more forgiving.
Pro Tips
Freeze your granita pan overnight. Starting with a cold surface means smaller, more delicate crystals form immediately instead of large icy chunks that crunch like gravel.
Bruise your mint before steeping. I tear the leaves roughly with my hands rather than chopping—the torn edges release oils differently, giving a rounder, less bitter flavor that doesn’t read as toothpaste.
Layer just before serving. The granita’s texture is ephemeral; nested in ice cream, it starts melting within minutes. I keep components separate in the freezer, then assemble in the moment.
My Secret Trick: I save a tablespoon of the mint-infused cream before churning and drizzle it over the finished dessert like a sauce—the raw cream tastes greener, more alive, against the cooked base.
How to Store Mint Ice Cream with Watermelon Granita
- Store mint ice cream in an airtight container with parchment pressed directly onto the surface to prevent ice crystals; keeps up to 2 weeks at 0°F.
- Keep granita in its shallow pan, covered tightly with plastic wrap, for up to 5 days; the texture stays best when scraped fresh before each serving.
- Do not store assembled desserts—the granita melts into the ice cream, creating an unpleasant slush.
- If granita becomes too solid, let it sit at room temperature for 5 minutes, then re-scrape with a fork to restore texture.
Nutritional Benefits
Mint ice cream with watermelon granita carries more virtue than most desserts I make. Watermelon brings lycopene and serious hydration, while fresh mint has actual digestive properties that my stomach notices. The cream and sugar are what they are—this isn’t health food—but at least the fruit and herbs aren’t lying about their origins.
FAQs
Can I use peppermint instead of spearmint?
Spearmint gives that classic ice cream flavor; peppermint tastes medicinal and sharp. If peppermint is all you have, use half the amount and add a tiny bit of vanilla to soften the edge.
Why is my granita freezing into a solid block?
You’re not scraping often enough or your freezer is too cold. Set a timer for 30-minute intervals, and move the pan to a slightly warmer spot if needed.
Do I really need to run the Creami twice?
For this dairy base, yes. The first spin gets you soft-serve; the second incorporates air properly and eliminates any graininess from the mint infusion.
Can I make this without a Ninja Creami?
Yes, but mint ice cream with watermelon granita works best with the machine’s specific texture. Without it, churn in any ice cream maker, then freeze 4 hours before serving.

Conclusion
This dessert lives in the space between lazy and deliberate—most of the work is waiting, watching, scraping. When I finally taste it, standing at my kitchen counter with the freezer still open, I’m always surprised by how completely it delivers on its promise. If summer had a flavor, this would be it. For another bright, clean finish to a heavy meal, my lemon sorbet has never failed me.
