Yep. For the traditional baked bean flavor you gotta start with the white navy beans. Maybe cannellinis could be substituted. And I saw one recipe that used lima beans.
I've found that a slow cooker is a great way to cook beans. Just make sure that once things start to thicken up you make sure to stir them every half hour or so. And rotate the crock a quarter turn to avoid hot spots. Obviously a half turn if it is an oval crock.
I've also found that the soaking in 42 changes of water really doesn't do that much to decrease either cooking time or gas. I rinse the beans, and toss 'em in. That is for either crock pot or stove top.
Beans, water, onion, bacon, dark brown sugar, molasses, salt, pepper, catsup, and I like a touch of cider vinegar.
