Watermelon Agua Fresca

Pro tips

• Chill your pitcher and serving glasses beforehand so the drink stays cold longer without over-diluting from melted ice.
• Use the sweetest, ripest watermelon available—taste before blending and reduce sugar if the melon is already very sweet.
• Strain the blended mixture through a fine-mesh sieve for a smoother, less pulpy texture, or leave it slightly thick for more body.
• Add ice only just before serving to prevent the drink from becoming watery as the ice melts.

Substitutions

• Lime juice → Lemon juice (1:1, slightly more acidic)
• Granulated sugar → Honey or agave nectar (reduce to 1/3 cup, stir well to dissolve)
• Seedless watermelon → Watermelon with seeds (strain after blending to remove seeds)
