Cook's notes: You may need a lot more broth. It depends on the configuration of your slow cooker. When I used my old slow cooker that is smallish and the perimeter of the vessel is round, I only need 32 ounces of broth. When I use my much larger slow cooker that has an oval-shaped vessel, I need much more broth to cover the beans. The broth turns out to have a delicious flavor, so if I end up with more, the finished dish is soupier. That’s not a complaint.
