Have you seen the viral Watermelon Shaved Ice? It’s currently notching up 75+ million views on social media, but the comments aren’t great — from “guys it’s not good” to “the only thing you’ll taste is the syrup”. The original recipe (by @itsvegansis) uses frozen watermelon, lime, maple syrup, and a sprig of mint. Refreshing? Sure. But also a little plain. I wasn’t put off though. Upon closer inspection, I realised the problem: it needs more flavour, more texture, and a bit of oomph. So I put my spin on it. I’ve added a basil sugar syrup, kept the limes (because watermelon and lime are magic together), and finished with pistachios and a spoonful of soy vanilla yoghurt.

And before you say, “Madalin, not everything has to be high protein” — you’re right, it doesn’t. But here’s the thing: the yoghurt addition doesn’t just bump up protein, it actually improves the dish. It adds creaminess, balances the sweetness, and makes the granita taste complete. If protein isn’t your vibe, swap it for coconut yoghurt — richer, creamier, and still delicious.

Why I sneak protein into snacks + desserts 🍪✨

Most people save protein for main meals, especially dinner. But your body actually uses protein better when you spread it out across the day. Loading up at dinner means your muscles can’t use it all in one go. By adding smaller amounts at breakfast, in snacks, or even in dessert, you give your body a steady supply to repair, rebuild, and keep you energised.

It also means:

• You stay fuller for longer (bye-bye pantry raids).
• Your energy and blood sugar stay balanced (no post-cake crash).
• Hitting your protein goal feels way easier without needing massive portions at one meal.

I know the current obsession with protein can sometimes feel a bit “diet culture,” but the truth is protein matters — especially on a plant-based diet. That’s why I love sneaking it into recipes like this one. And if you’re looking for more protein-rich meals and desserts, check out my recipe library!

Main Ingredients & Why We Use Them

• Watermelon – Naturally sweet, juicy, and hydrating. Freezes beautifully to create light, fluffy ice crystals.
• Lime (zest + juice) – Adds brightness and a hint of tang that balances the sweetness of the melon.
• Caster Sugar – Optional, but helps boost sweetness if your watermelon isn’t very ripe.
• Fresh Basil Leaves – Infuse the syrup with a herbal, aromatic note that pairs perfectly with watermelon.
• White Caster Sugar & Water (for syrup) – Create a simple base to extract and carry the flavour of the basil. Many people use maple syrup instead (and you can), but there’s this fear of white sugar over “natural” sugar. Let me remind you that both sugars cause the same response in the body — they’re broken down into glucose and fructose. The difference is more about flavour and texture than about being “better” or “worse.” For this recipe, caster sugar keeps the syrup clear, light, and allows the basil to shine.
• Pistachios – Provide crunch and nutty richness, balancing the lightness of the granita.
• Soy Yoghurt– Adds creaminess, making the dish feel more indulgent and satisfying. Soy coconut yogurt increases the protein, but if you don’ t care for protein you can replace with coconut yogurt or condensed coconut milk.
• Edible Flowers or Extra Basil – For garnish and visual appeal.

Watermelon Granita Ingredients

How to Make It

First, freeze the watermelon chunks until solid. While that sets, prepare the basil syrup by simmering sugar and water, then steeping fresh basil and blending to a vivid green. Once your melon is frozen, grate it into icy flakes then mix with lime juice, and a touch of sugar if needed. Fluff with a fork and return to the freezer briefly. To serve, spoon the granita into bowls, drizzle with basil syrup, sprinkle with pistachios, and finish with a dollop of creamy yoghurt.

Variations and Substitutes

You can swap lime for lemon for a softer citrus note. Try mint instead of basil for a different herbal twist. For extra indulgence, drizzle over coconut condensed milk instead of yoghurt. You can also add a pinch of chilli or Aleppo pepper for a subtle kick.

Equipment

You’ll need a freezer-safe tray to set the watermelon and a saucepan to make the basil syrup. A lemon zester works well for creating fine ice, and a sieve will help strain the syrup for a smooth finish.

How to Serve It

Serve this granita in shallow bowls or elegant glasses with yoghurt on the side, pistachios sprinkled over, and a garnish of basil or edible flowers. It’s perfect as a light dessert after dinner or as a cooling afternoon treat on a hot day.

How to Store It

Granita can be made in advance and stored in the freezer for up to 3 days. Just fluff with a fork before serving to restore its icy texture. The basil syrup will keep in the fridge for up to 3 days in a sealed jar.
