Watermelon Mint Cooler

About this recipe

A blender, a ripe watermelon, and four minutes—this is the no-cook cooler we make on repeat through the hottest weeks, when the kitchen is already too warm to turn on the stove. A pinch of black salt is the step most recipes miss entirely, and it's also the moment the cooler transforms from pleasant to genuinely craveable. Black salt doesn't make it taste salty; it deepens the melon's sweetness and replaces the electrolytes your body loses in extreme heat. Top with sparkling water just before serving for lift that keeps the drink from tasting flat or cloying. Watermelon is almost entirely water with enough natural sugar that it needs no sweetening beyond what the fruit brings. Lime juice adds brightness without tasting citrus-forward; it cuts the melon's natural sweetness and adds a subtle sharpness that makes you want another sip. Fresh mint scattered coarsely on top perfumes the drink without overwhelming it. The finished cooler tastes refreshing because of its simplicity, not in spite of it. Choose a melon that's heavy for its size and has a deep hollow sound when you tap it—that's where the sweetness lives. Chill the melon before blending; it makes the cooler properly cold without needing as much ice. Blend until juicy and smooth, then taste before adding salt; you might need more or less depending on the melon's sweetness. Some families strain the blended juice through a sieve for a cleaner drink; others leave it pulpy for extra fibre. Both approaches work beautifully. Serve in tall glasses over plenty of ice, with fresh mint scattered on top and a lime wedge on the rim. A splash of sparkling water just before serving adds effervescence that makes the cooler feel special. Store the blended juice in the fridge for up to two days, but add the sparkling water and mint only at serving time. This cooler freezes beautifully in popsicle moulds for a slushy version that's perfect for children.
