First, soak your beans overnight, changing the water once or twice.

Next, cook your bacon until almost finished. (It will cook the rest of the way in the beans.) Save about 1- 2 tablespoons of the bacon grease.

Next, drain your beans. Add the broth to your beans, bring to a boil, reduce heat to medium low and cook until tender. About 1 hour. Stir gently occasionally. Most of the liquid should have boiled out.

Preheat your oven to 350 degrees.

In your dutch oven, heat the bacon grease and then add the onions on medium low. Cook until soft, about 7-10 minutes. Add the garlic and cook until fragrant, about 30 seconds.

Add the beans, ketchup, maple syrup, mustard, and vinegar and stir to combine.

Bake in the oven for 45 minutes to one hour.

Add salt to taste if needed.
