This is adapted from a Rick Bayless recipe from his great cookbook, Mexican Everyday.
Serves 4
INGREDIENTS
1 to 1 ½ pounds pork tenderloin
2 T canola oil
2 fresh poblano peppers
1 medium onion
3 garlic cloves, pressed
5-6 tomatillos
3/4 cup beef broth OR 2/3 cup water
1 t hickory smoke
1 T Worcestershire sauce
1/2 cup cilantro, chopped
Kosher salt
METHOD
Preheat broiler.
Roast the peppers over an open flame or under a broiler under they are uniformly blackened and have softened a bit. You can do this right on your stovetop by setting the peppers directly above the flame.
When done, place in a bowl and cover. Allow them to cool.
Remove husks from tomatillos, rinse, and place on a sheet pan. Broil for about 5-6 minutes, turning midway, until browned. Reserve.
Turn down oven to 200F
Peel and halve the onion and cut it crosswise into strips about 1/4-inch wide. Reserve.
Rub the blackened skin off the poblanos, remove the stems and seeds inside and rinse under water to remove the excess charred skin and seeds. Slice into long strips, about 1/4-inch wide, and then chop into pieces about two inches in length. Reserve.
Pat the tenderloin dry with paper towels and trim away all visible fat. Cut the tenderloin into 1-inch cubes and sprinkle liberally with kosher salt.
Heat the canola oil in a Dutch oven or large skillet (12 inches). And pork (do this in batches if necessary, to avoid overcrowding) and brown all over. Transfer to a plate and reserve.
Add the onion and poblano strips to the same pot and saute over a medium flame for 5 minutes or so. Add the garlic and continue to cook for another 2 minutes. Add the tomatillos, smashing them up with a wooden spoon. Add beef broth (or water), Worcesteshire, and hickory smoke and bring to a boil. Cover and transfer to the oven. Cook for 2-3 hours.
Add cilantro and taste for seasoning, adding more salt as needed. Serve with warmed corn tortillas.
