Navy beans are cooked with bacon and molasses to create this classic side-dish recipe.
1. Drain beans; place in a large saucepan. Cover with water by 2 inches; stir in baking soda. Bring to a boil over medium-high heat; boil for 15 minutes, skimming off any foam that accumulates.
2. Meanwhile, heat a 10-inch nonstick skillet over medium-high heat. Add bacon to skillet; cook 4 minutes, stirring occasionally. Add onion to pan; cook 5 more minutes, stirring almost constantly.
3. Drain beans and transfer to slow cooker insert. Top with bacon mixture. Stir in molasses, sugar, boiling water and 1 teaspoon of the dry mustard. Cover; cook on HIGH for 5 hours or LOW for 6-1/2 hours.
4. Remove cover; stir in remaining 1 teaspoon dry mustard, the cider vinegar and salt and pepper; serve immediately.
