Ingredients

  • 1 pound dry pinto beans, rinsed
  • 6 plum tomatoes, cut in half lengthwise
  • 4 frying peppers, cut in half lengthwise, cored, deribbed and seeded
  • 1 hot red pepper, seeded and cut across in 1/4-inch slices
  • 1 teaspoon dry mustard
  • 3 tablespoons molasses
  • 4 teaspoons salt, plus more to taste
  • 1 teaspoon freshly ground black pepper
  • 1 teaspoon olive oil or bacon fat
  • 1 medium onion, minced
  • 1 1-pound flank steak
  • 2 teaspoons kosher salt
  • 1 teaspoon coarsely ground black pepper

Method

  • Place the beans in a large, heavy-bottom pot.
  • Cover with 2 inches of water.
  • Bring to a boil for 3 minutes.
  • Remove from heat.
  • Cover and let stand for 2 hours.
  • Preheat the oven to 400 degrees.
  • Place the tomatoes and frying peppers, skin side up, on a baking sheet.
  • Roast for 25 minutes.
  • Carefully transfer the vegetables with their juices to a food processor or blender.
  • Add the hot red pepper.
  • Puree until smooth.
  • Set aside.
  • In a small bowl, stir together the mustard, molasses, salt and pepper.
  • Set aside.
  • Drain beans, discard liquid and dry the pot.
  • Set beans aside.
  • Place the olive oil or bacon fat in the pot and warm over medium heat.
  • Add the onion and cook until soft, about 5 minutes.
  • Add the beans to the onion.
  • Pour in enough water to barely cover the beans.
  • Stir in the tomato-pepper puree and the molasses mixture.
  • Cover.
  • Bake until tender, about 1 3/4 hours, adding water as needed to keep beans very moist but not soupy.
  • Add salt to taste.
  • Fifteen minutes before serving, season the steak with 1 teaspoon salt and pepper.
  • Set aside.
  • 10 minutes before serving, place a cast-iron skillet over high heat.
  • Add the remaining salt to the skillet.
  • Heat until hot.
  • Quickly sear the steak, allowing it to cook 2 to 3 minutes on each side, depending on its thickness and how you like your steak cooked.
  • Remove from pan.
  • Let stand for 5 minutes.
  • Slice and serve around beans.
