Callo de Hacha al Mojo de Ajo

This is from Sonora. Specifically from the coast around Bahia Kino and Guaymas, where the pangas come in at dawn with the callo de hacha pulled from the bed of the Gulf of California, what the Sonorenses call the Mar de Cortes. This is not the small bay scallop you find in a supermarket freezer. The callo de hacha is the white adductor muscle of the pen shell, a triangular bivalve that grows buried in the sand. The divers go down for them by hand. That is the dish before you have started cooking.

The Noroeste, Sonora, Sinaloa, Baja California Sur, eats seafood differently than the south. There is no achiote, no banana leaf, no recado rojo. The cooking is direct: butter, garlic, lime, a hot pan. You are not building a sauce for hours. You are getting out of the way of an ingredient that came out of the sea this morning. If your callo is fresh and sweet, four ingredients is enough. If your callo is not fresh, no recipe can save it. Si no conoces el mercado, no conoces la cocina.

The flour tortilla on the side is also Sonoran, not a substitution. The north eats wheat. The wheat came in with the Spanish missions and never left, and a Sonoran will hand you a flour tortilla with their callo de hacha and look at you funny if you ask for corn. Cada estado, su propia cocina. The mojo de ajo, butter melted slowly with garlic until it turns sweet, then poured hot over the seared scallop, is the technique that defines marisco cooking from Mazatlan up through Puerto Penasco. Get the garlic pale gold, never brown. Sear the callo hard and fast, never long. Eat it the moment it leaves the pan. Recetas probadas y garantizadas.
