Here is a recipe I copied but never tried. Perhaps it is close?
SPICY COWBOY BEANS
From Bon Appetit, 7/95. Seed the jalapeño to cut the spiciness, if desired. Garnish with sour cream and chopped cilantro
1 lb. dried pinto beans
1 1-lb. center-cut ham slice, cut into ½-inch cubes.
1 ¼-lb piece of salt pork, rind scored in crisscross pattern (or just the rind?)
1 large onion, chopped
6 tbs. chili powder
2 garlic cloves, minced
1 jalapeño chili, minced
2 tsp. Worcestershire sauce
1 tsp. Tabasco
1 bay leaf
In Dutch oven, cover beans with 3 inches water and bring to boil. Boil 2 minutes. Cover and let sit 1 hour. Drain.
Return to pot, cover with 2 inches of water and add remaining ingredients. Bring to boil, then simmer slowly until beans are tender and liquid thickens, stirring frequently, about 3 hours.
Discard salt pork and bay leaf. Season with salt and pepper. (Can be made a day ahead and reheated).
