Castacan Yucateco

Castacan is Yucateco. Not Mexican-generic. Yucateco. The Peninsula has its own grammar, recado, sour orange, banana leaf, pib, habanero, and castacan sits squarely inside it. You eat it at the cantinas in Merida on a Saturday afternoon, folded into a hand-pressed corn tortilla with pickled red onion and a spoonful of xnipec that makes you sweat at the temples. That is the dish.

The technique is pork belly slow-cooked in its own lard until the meat is tender, then crisped under high heat so the skin shatters when you cut it. This is not bacon. This is not American chicharron. This is the Peninsula's confit, and it carries the marks of Yucatan everywhere: the naranja agria in the seasoning, the oregano yucateco, the habanero in the salsa, the cebolla morada turned magenta by the sour orange. If you substitute regular orange and skip the sour, you have made something. You have not made castacan.

My first castacan was at a small cantina off Calle 47 in Merida, served on a piece of butcher paper with a stack of tortillas and a clay bowl of xnipec. The senora at the comal pressed the tortillas one at a time and would not let me leave until I had eaten at least three tacos. She told me that her father, who taught her, used to say the dog's nose tells you when the xnipec is right. That is where the name comes from. Saber cocinar es saber vivir.
