You know that moment in the middle of July when friends come over for lunch and the only drink you have to offer is tap water or a half-empty carton of juice? This watermelon-tomato juice solves that problem in five minutes flat. And it always makes an impression.

First, the color. A deep red, somewhere between ruby and pomegranate—not the artificial red of a syrup, but the real, saturated red that comes from perfectly ripe fruit. In the glass, it’s dense, almost velvety. The scent rising from the blender when you lift the lid is sweet but not cloying, with that slight aquatic undertone of fresh watermelon. One sip, and you feel the coolness go straight down.
