Few drinks are as instantly refreshing as a tall glass of watermelon agua fresca, and this version is bright, lightly sweet, and absolutely stunning to serve on a warm day. Fresh watermelon blends up with mint, lime juice, honey, and just a touch of sea salt, creating a drink that tastes like summer in a glass. The sea salt here is fine and used in a very small amount, which keeps it well within the boundaries of a low-iodine approach — no iodized table salt, no processed additives, just clean, whole ingredients throughout. Managing iodine intake can feel restrictive when it comes to packaged beverages, which often contain additives or ingredients that are harder to track, so blending your own from scratch is a genuinely smart move. Straining the blended mixture through a fine-mesh sieve gives the final drink a silky, smooth texture that feels far more polished than the effort required. A squeeze of extra lime or a drizzle more honey lets you dial in the flavor exactly to your taste before serving. Pile the glasses high with ice, tuck in a sprig of mint, and you have something that looks and tastes like it came from a café counter.
