Salsa Molcajeteada para Tlayudas

This salsa is from the Valles Centrales of Oaxaca. Specifically the markets of the city itself, the Central de Abastos and the 20 de Noviembre, where the women who run the tlayuda comales keep a molcajete at their elbow and grind salsa fresh through the lunch hour. It is the salsa that goes on a tlayuda. Not a salsa verde from Jalisco. Not a salsa roja from Mexico City. This one. Asi se hace y punto.

The technique is the recipe. Whole tomate, chile serrano, garlic, and onion charred dry on a comal until the skins blister and blacken, then ground by hand in the molcajete. No oil on the comal. No water in the salsa. No blender. The molcajete is volcanic basalt and the porous surface tears the vegetables apart in a way no blade ever does, releasing oils and flavors a blender pulverizes past. A blender salsa is a different thing. It has its place. This is not its place.

My mother was from Jalisco and she did not make this salsa. I learned it from a senora named Dona Petra at the 20 de Noviembre, who watched me grind once, took the tejolote out of my hand, and showed me how to press, not stir. Press, do not stir. The motion matters. Press breaks the tomate without liquefying it and that is why a Oaxacan salsa molcajeteada has texture you can feel against your teeth, not just taste. Cada estado, su propia cocina, and within Oaxaca, this salsa is the foundation of the table.
