1Combine all ingredients in a small saucepan over medium heat. Bring to a boil, stirring until ingredients are completely incorporated. Reduce heat to low and gently simmer until flavors have melded and sauce has thickened enough to coat the back of a spoon, about 30 to 40 minutes.
2Remove from heat and let cool to room temperature. If not using right away, cover and refrigerate for up to 2 weeks.
Steve Sando, bean impresario behind Rancho Gordo, outlines the steps from beans in a bag to glorious pot o’ beans. Dried beans may not be fresh, per se, but the ones you're using shouldn’t be more than two years old. Soak them first, and then use the soaking water to cook them. A quick, hard boil followed by a long, slow simmer will get them cooked up right. (Click here for Steve's bean-cooking recipe.)
