Step 1

Bring first 8 ingredients, 1/4 tsp. salt, and, if desired, serrano chile to a boil over medium-high heat in a Dutch oven. Cover and cook, stirring occasionally, over medium-low heat 3 hours or until beans are tender. Stir in remaining 1 tsp. salt. Remove and discard salt pork and chile before serving.

Step 2
