Kitchen Tools Needed
This recipe requires minimal tools—perfect for beginners!
- Blender or food processor
- Fine-mesh strainer (to remove seeds and pulp if desired)
- Large mixing bowl
- 9×5-inch loaf pan or shallow baking dish
- Spatula or whisk
- Parchment paper or plastic wrap (to cover surface)
Step-by-Step Instructions: How to Make Watermelon Berry Granita
- Prepare the Fruit: Cut watermelon into 1-inch cubes. If using frozen berries, let them soften at room temperature for 10–15 minutes. For best results, use slightly thawed watermelon to prevent icy granules.
- Blend Until Smooth: In a blender, combine watermelon, mixed berries, lemon juice, honey (or maple syrup), vanilla, and a pinch of salt. Blend on high until completely smooth—about 1–2 minutes. If you prefer a smoother texture, strain the mixture through a fine-mesh sieve to remove seeds and fibrous bits.
- Pour Into Freezer Dish: Transfer the liquid into a loaf pan or shallow dish. Smooth the top with a spatula for even freezing.
- Freeze & Scrape: Place in the freezer for 1 hour. After one hour, use a fork or whisk to scrape the surface, breaking up any ice crystals. This step is key to achieving that classic granita slush texture.
- Repeat Every 30 Minutes: Continue freezing and scraping every 30–45 minutes for 2–3 hours total. Each scrape aerates the mixture and prevents large ice crystals from forming.
- Serve Immediately: Once the granita has a soft-serve consistency, scoop into glasses or bowls. Garnish with fresh berries and a mint leaf for an Instagram-worthy finish.
Pro Tips for Perfect Granita Every Time
- Use Ripe Watermelon: The sweeter the watermelon, the less sugar you’ll need. Look for firm, heavy melons with a creamy yellow spot on the rind.
- Don’t Over-Sweeten: Taste the mixture before freezing. If it’s too tart, adjust with a bit more honey—but remember, freezing enhances coldness and can mute sweetness.
- Scraping Is Crucial: Skipping this step leads to icy, granular texture. Set a timer—don’t skip!
- Prevent Ice Crystals: Cover the surface with plastic wrap directly on the liquid to minimize air exposure during initial freezing.
- Make Ahead: Granita freezes well for up to 2 weeks. Just store in an airtight container.

Storage and Reheating Tips
Granita doesn’t “reheat”—but it does store beautifully! Keep in an airtight container for up to 2 weeks. When ready to serve, let it sit at room temperature for 5 minutes, then scrape again. If it’s too hard, microwave for 10-second intervals until softened.
Frequently Asked Questions About Watermelon Berry Granita
Can I make watermelon berry granita without a blender?

Up to 2 weeks if stored properly in an airtight container. Always scrape before serving to refresh the texture.
