Gelo di melone is a Sicilian watermelon pudding made by simmering fresh watermelon juice with sugar and cornstarch until it thickens, then chilling it in cups until firm. No eggs, no cream, no dairy at all, just juice and starch doing the work.
You’ll see it all over Palermo’s street food scene in August, sold from carts and market stalls, usually dusted with cinnamon and studded with dark chocolate chips and chopped pistachios. Some versions add jasmine flowers or a splash of orange blossom water, but the base recipe stays the same everywhere.
The part people get wrong is the cooking stage. If you pull the pot off the heat too early, the starch never fully activates and the pudding stays soupy even after hours in the fridge. It needs a real simmer, not just a warm-through.
Once you get the ratio of juice to cornstarch right, this is a five-minute stovetop job followed by a long nap in the fridge. Good for using up a watermelon that’s gone slightly past its best for eating fresh.

Ingredient Notes
- watermelon: Pick a ripe, sweet melon since the pudding’s flavor depends entirely on the juice. Seedless melon saves you the straining step of picking out black seeds before blending.
- cornstarch: This is what sets the pudding without eggs or gelatin. Potato starch works as a swap in the same amount, though the set will be slightly softer.
- granulated sugar: Adjust up or down depending on how sweet your melon already tastes. Start with less and taste the warm juice before adding the rest.
- cinnamon stick: Infuses the base while it cooks and gets pulled out before chilling. Ground cinnamon dusted on top at serving works too if that’s what you have.
- dark chocolate chips: The classic Sicilian garnish alongside pistachios. Chop a chocolate bar roughly if you don’t have chips on hand.
- pistachios: Use unsalted, shelled pistachios and chop them coarsely so they stay crunchy against the soft pudding.
Gelo di Melone: Creamy Sicilian Watermelon Pudding
Ingredients
Method
- Blend the watermelon chunks in batches until smooth.
- Strain the puree through a fine-mesh sieve into a bowl, pressing the pulp with a spoon to get all the juice out. Discard the pulp. You should have about 900 ml of juice.
- In a 3-quart / 2.8 L saucepan, whisk the cornstarch, sugar, and salt together, then whisk in about 200 ml of the cold watermelon juice until completely smooth with no lumps.
- Add the rest of the watermelon juice and the cinnamon stick. Set the pan over medium heat.
- Cook, whisking constantly, until the mixture reaches a gentle simmer around 90 C / 194 F and thickens enough to coat the back of a spoon, about 8 to 10 minutes.
- Remove the cinnamon stick and take the pan off the heat.
- Pour the warm mixture into 6 serving cups or ramekins, about 180 ml each.
- Let the cups cool at room temperature, uncovered, for 20 minutes.
- Cover and chill for at least 4 hours, or overnight, until fully set.
- Before serving, top each cup with chocolate chips, chopped pistachios, and a light dusting of cinnamon if using.
Notes
- Strain the blended watermelon well, seeds and pulp make the texture grainy.
- Whisk constantly once the pan is on the heat, cornstarch scorches fast if left alone.
- Chill at least 4 hours, overnight gives the cleanest set for slicing or scooping.
- Add toppings just before serving so pistachios stay crunchy against the soft pudding.
Tips for Success
- Taste your watermelon juice before adding sugar since ripeness swings the sweetness a lot batch to batch.
- Whisk the cornstarch into cold juice first, never sprinkle it straight into the hot pan or it clumps.
- Keep whisking constantly over medium heat so the bottom doesn’t scorch or stick to the pan.
- Pour into serving cups while the mixture is still warm, it sets flatter and skips a messy transfer later.
- Chill uncovered for the first 20 minutes so condensation doesn’t pool and water down the surface.
Variations
- Add a jasmine-infused syrup or a few drops of orange blossom water for the traditional Palermo street version.
- Swap the pistachios for toasted almonds and use white chocolate instead of dark for a lighter look.
- Layer the pudding in tall glasses with fresh diced watermelon between layers for extra texture and color.
Storage and Reheating
Gelo di melone keeps 3 to 4 days covered tightly in the fridge. Keep the topping of chocolate and pistachios off until just before serving so it doesn’t go soft sitting in the fridge.
This pudding is meant to be eaten cold straight from the fridge, so there’s no reheating step here. Freezing isn’t a good option either, since the cornstarch structure breaks down on thawing and the pudding weeps into a watery, grainy mess.
If you want to get ahead, cook and chill the base a day in advance in its serving cups, then add the toppings right before you bring it to the table.
Serving Suggestions
Serve gelo di melone straight from the fridge in small bowls, glasses, or the classic Sicilian ceramic cups, with a fresh scatter of chocolate chips and chopped pistachios on top.
A dusting of ground cinnamon or a few crumbled cantucci biscotti on the side add contrast against the soft pudding. Iced coffee or a classic Cynar Spritz works well alongside it on a hot afternoon.
For a bigger spread, set out small cups of gelo di melone next to lemon granita so guests can pick between the two cold Sicilian classics.
FAQ
Why is my gelo di melone runny instead of set?
It’s usually undercooked cornstarch. The mixture needs to reach a real simmer and thicken visibly, coating the back of a spoon, for about 8 to 10 minutes on the stove. Pulling it off too early or using too little starch for the amount of juice leaves it soupy even after a long chill.
Can I use potato starch instead of cornstarch for gelo di melone?
Yes, potato starch works in the same 75 g amount and is actually traditional in some Sicilian households. The set will be a touch softer and less glossy than cornstarch, but the flavor and texture are close enough that most people won’t notice the swap.
How long does gelo di melone last in the fridge, and can I freeze it?
It keeps 3 to 4 days covered in the fridge, best eaten within the first two for the cleanest texture. Freezing isn’t recommended since the starch breaks down on thawing and the pudding weeps liquid, turning grainy and watery instead of silky.
What goes well with gelo di melone besides chocolate chips and pistachios?
Crumbled cantucci biscotti, a dusting of ground cinnamon, or a few candied jasmine flowers all work as traditional finishing touches. Lemon granita on the side makes a good pairing if you’re serving a bigger spread of cold Sicilian desserts.
Is gelo di melone gluten free and dairy free?
Yes, the base recipe has no flour, gluten, dairy, or eggs, just watermelon juice, sugar, and cornstarch. Double check your chocolate chips are labeled gluten free if you’re cooking for someone with celiac disease, since some brands process on shared lines.
What’s the difference between gelo di melone and biancomangiare?
Gelo di melone is set with watermelon juice and cornstarch and has a pale pink color and fruity flavor, while biancomangiare is a white Sicilian pudding made with almond milk instead of fruit. Both use the same starch-thickening technique but land on opposite ends of the flavor spectrum.
