Watermelon Agua Fresca

• 1 cup very cold water (about 8 ounces/250 milliliters)
• 4 cups cold, ripe, 1 1/2-inch (4-centimeter) watermelon chunks, preferably seedless (about 24 ounces/680 grams)
• 1 tablespoon freshly squeezed lime juice (about 1/2 ounce/15 milliliters)
• Pinch of salt
• 1 1/2 tablespoons sugar, or to taste, optional (about 3/4 ounce/18 grams)

1. Place the water, watermelon, lime juice, salt, and sugar, if using, in a blender and puree the fruit well, roughly 30 seconds.
2. Taste the agua and correct the seasoning with additional lime juice or sugar if desired, pour into a pitcher, and chill for at least 1 hour.
3. Just before serving, stir the agua to blend, pour into a chilled glass or glasses, and serve at once.
4. Watermelon-Cucumber Variation
