Crema de Chile Poblano

This is from Puebla. Specifically from the highland kitchens that built their entire culinary identity around the chile poblano, the heart-shaped, deep-green chile that gives this soup its name, its color, and its reason to exist. There is no version of this soup that uses a different chile. Substitute and you have made something else.

The poblano has to be charred over open flame until the skin blisters black. Then sweated, peeled, seeded, and blended with sweated onion, garlic, a few leaves of epazote, and warm caldo de pollo. The puree gets fried in lard until the fat beads at the edge, the same principle that gives a mole or a salsa its depth. Crema mexicana goes in at the end, tempered and stirred over the lowest heat so it does not break. Finish with cubes of queso panela, which soften in the bowl without melting, and a scatter of sweet elote tierno. This is what poblano kitchens serve when they want to comfort someone.

My mother made crema de poblano on cold nights in Colonia Roma. She used the small blue blender that sat on the counter for thirty years and a clay cazuela that her own mother had brought from Jalisco. She would not let me near the chiles on the flame until I was twelve, and then she would not let me leave the stove until I had charred all six. She used to say a cook who is afraid of fire is not yet a cook. Saber cocinar es saber vivir.

If the poblanos at the mercado look pale, thin-walled, or shriveled, do not make this soup today. The poblano carries everything. Pregúntale a las señoras del mercado, they will tell you which week the chile is right.
