Salsa de Cuajada del Istmo

This salsa is from the Istmo de Tehuantepec, the narrow waist of Oaxaca where the Pacific almost touches the Gulf, and specifically from Juchitan, the Zapotec city where the women run the markets and the kitchens and most of the visible economy. It is not a salsa from Oaxaca de Juarez. It is not a salsa from the Sierra. It is istmena, and within Oaxaca that distinction matters.

Two ingredients carry the dish. Cuajada is a fresh, lightly pressed curd cheese, mild and slightly tangy, made in the ranchos around Juchitan and sold in the Mercado 5 de Septiembre wrapped in banana leaf. It is not queso fresco and it is not requeson. The texture is its own. Chile pasado is a fresh chile that has been laid out on a rooftop and dried whole in the istmeno sun until the skin shrivels and the flavor concentrates into something between fresh and dried, with a faint smoke that has nothing to do with fire. You will not find chile pasado at most US markets. If you cannot get it, chile costeno rojo from the Oaxacan coast is the honest substitute. A smoked chipotle is not. Do not come to me with chipotle.

The technique is the metate, or the molcajete if you do not have a metate. The chile and salt are ground to a coarse paste, then folded by hand into the cuajada. No blender. The texture of the stone-ground chile against the soft cheese is the entire reason the dish exists. My mother never made this. She was from Jalisco. I learned it in 2009 from a woman named Na Berta who sold cuajada at a corner of the Juchitan market and who watched me grind for ten minutes before she nodded once and said, ya. That nod is what I am trying to teach you. Cada estado, su propia cocina, and within Oaxaca, the Istmo is its own country.
