In a large bowl, combine the coriander, paprika and cumin and toss with the pork cheeks. Season with salt and pepper.
In a large enameled cast-iron casserole, heat 2 tablespoons of the oil. Add half of the pork and cook over moderately high heat, turning once, until browned, about 8 minutes. Transfer the pork to a plate. Add the remaining 2 tablespoons of oil and brown the remaining pork over moderate heat. Transfer the pork to the plate.
Add the bacon to the casserole and cook over moderate heat, stirring occasionally, until browned and slightly crisp, about 7 minutes. Add the onion, garlic, jalapeños and bell peppers and cook, stirring occasionally, until the vegetables are softened, about 5 minutes.
Return the pork cheeks to the casserole along with any accumulated juices. Add the ale, chicken stock, tomatoes, chipotles, black-eyed peas and cinnamon stick and bring to a boil. Cover and cook over very low heat until the meat and beans are tender, about 2 1/2 hours. Season the chili with salt and pepper. Spoon off the fat from the surface and discard the cinnamon stick. Serve the chili in bowls. Pass the smoked cheddar, cilantro and crème fraîche at the table.
