Agua de Jamaica Yucateca

This is the Yucatán Peninsula's most-poured drink. From Mérida to Valladolid to Campeche, the jarra of jamaica sits on every cocina económica counter at lunchtime, deep ruby red, sweating in the tropical heat. The Peninsula does not drink jamaica the way the rest of Mexico does. Here it carries canela and pimienta gorda, the warm baking spices that mark almost every Yucatecan kitchen, the same pimienta gorda that goes into the recado for cochinita pibil and the relleno negro. Cada estado, su propia cocina, and the Peninsula puts its spice cabinet into the agua fresca.

The technique is simple and unforgiving. You do not boil jamaica. You bring the water to a boil with the spices, kill the heat, and steep the flowers off the burner. Twenty minutes, covered. Boiling water cooks the tannin out of the petals and turns the agua bitter and brown. Hot water steeped slowly pulls the color and the flavor clean. This is the difference between an agua de jamaica that tastes like flowers and one that tastes like burnt tea. No me vengas con atajos.

Piloncillo is the sweetener, not white sugar. The dark cone of unrefined cane gives the agua a depth that granulated cannot reach, a faint smokiness that meets the canela halfway. In Mérida the señoras serve it in heavy glass jarras over crushed ice with a wedge of lima agria on the rim. The lima agria, that bitter orange the Yucatán uses in place of lemon, is what every Yucatecan thinks of when they taste this drink at home. If you cannot find lima agria, regular lime will work, but you should know what you are missing. Saber cocinar es saber vivir, and on a 35-degree afternoon in Mérida, knowing how to pour a glass of this is its own kind of survival.
