Few drinks hit as hard on a hot day as a properly made agua fresca, and this watermelon version is genuinely stunning — clear, bright pink, and bursting with fresh flavor. The trick of blending mint with cold water first ensures every sip carries that cool, herbal lift without any grassy bitterness. Fresh lime juice cuts through the natural sweetness of the watermelon beautifully, and straining the blended mixture through a fine-mesh sieve gives you that gorgeous, almost jewel-like clarity in the glass. A little optional honey lets you dial in the sweetness to your exact taste, which is a small detail that makes a big difference. For anyone navigating iodine restrictions, this recipe is a natural fit — it's built entirely from fresh fruit, citrus, herbs, and water, with no processed ingredients or additives to second-guess. It's the kind of drink that looks like it came from a fancy café but comes together in your own kitchen with almost no effort.
