Pork and Posole with Chipotles

Posole is dried corn treated with limestone, a traditional American food that predates the arrival of Europeans by some thousands of years. In its ground form it is the main ingredient in tortillas, but for some reason the whole kernels are largely ignored in this country outside of the Southwest. (Hominy, which is essentially the same thing, has a bit of a following in the South, but again mostly in its ground form: grits.) Posole is also the name of a soupy stew containing, well, posole. It can be varied in many ways, but it is always delicious and distinctive. If you have time, soak and cook the dried kernels yourself: Rinse the posole, then soak it in water to cover if time allows, for up to 12 hours; cook in boiling water to cover, stirring occasionally, for 1 hour and probably longer. Season with salt and drain. Canned posole (or hominy) is almost as good, and reduces the time it takes to make this soup to about an hour.
