Salsa de Soya y Chiltepín de la Chinesca

This sauce is from Mexicali, Baja California. Specifically from La Chinesca, the Chinatown that has fed that city since the 1920s, the largest Chinese community in Mexico for most of the 20th century, built by the workers who came up from Guangdong to dig the irrigation canals of the Mexicali Valley and stayed to open restaurants when the work was done.

This is not fusion. Fusion is what a chef does in a hotel kitchen when he wants to put his name on something. This is what happened over a hundred years when Cantonese cooks could not get the chiles they grew up with and started using the chiltepín that grew wild in the Sonoran desert across the river. They kept the soy. They kept the sesame oil. They added lime, garlic, white onion, and the wild chile of the noroeste. The sauce that came out the other end belongs to Mexicali and to nowhere else.

The chiltepín is the soul of this sauce. Pea-sized, wild, harvested by hand in the sierras of Sonora and northern Baja, it has a heat that arrives fast and disappears fast. That short heat is what makes the sauce work next to fried food. A long, lingering chile would bury the wontons. The chiltepín hits, gets out of the way, and leaves you reaching for the next bite.

My mother never made this sauce. She was from Jalisco and she did not know Mexicali. I learned it from a senora who ran a fonda inside La Chinesca for forty-three years, who taught me with a soy sauce bottle in one hand and a jar of chiltepines en vinagre in the other. She told me: "This is our food. Not Chinese food. Not Mexican food. Mexicali food." Cada estado, su propia cocina, and Baja California Norte built one nobody else has.
