Step 1

For the green chili: Cook the pork in some vegetable oil in a heavy-bottomed pot or Dutch oven over medium heat until the meat is browned on the outside and a little pink on the interior. Add the garlic and onion and cook until soft. Add the flour and stir until brown. Add some water (up to 1 cup) and adjust according to the desired thickness. Add the chicken broth and stir to combine. Add the canned tomatoes and chiles, roasted green chiles, serrano chiles, cumin, cilantro, cayenne, salt, black pepper and white pepper and bring to a boil. Turn the heat to low and simmer uncovered, stirring constantly, for 2 to 3 hours. If you need to thicken the chili, add more flour. If you need to thin it, add more broth.
