Few drinks are as instantly refreshing as a tall glass of this blended watermelon cooler, and the good news is it comes together with just a handful of simple, low-nickel ingredients. Watermelon, lime juice, a pinch of salt, and a touch of sugar are all you need — no nuts, seeds, whole grains, or legumes that tend to cause trouble for people managing nickel sensitivity. The process is beautifully straightforward: blend, strain, season, and serve. Straining the blended fruit through a fine-mesh sieve gives you a silky, jewel-toned drink that looks like something from a fancy café. A squeeze of fresh lime brightens the natural sweetness of the watermelon without overpowering it, and that small pinch of salt rounds everything out in the best way. Poured over ice with a lime wedge on the rim, it's the kind of drink that makes a hot afternoon feel completely manageable.

Add the watermelon cubes and cold water to a blender and blend on high until completely smooth, about 30–45 seconds.
Set a fine-mesh strainer over a large pitcher. Pour the blended watermelon through the strainer, pressing gently on the solids with a spoon to extract as much liquid as possible. Discard the pulp left in the strainer.
