I started with the recipe here. It is yummy.
2 c. White Beans (I had previously cooked them up from dry beans)
1/4 c ketchup
1/4 c molasses
2 T brown sugar
1 t Worcestershire Sauce
1/2 t salt
1/8 t ground black pepper
1/4 t chili powder
1/4 t ground mustard
1/8 t (maybe closer to 1/16 t) celery seed
1 onion, chopped
Enough water to cover, but not drown
Place all in crock pot and simmer, stirring regularly, until thickened and onions are done - approx 3 hours. This doesn't make a ton, which also makes keeping the temp regulated in the crock pot a little difficult. You may want to double the recipe or choose a different cooking method (oven?). You'll also want to taste it as things come along and adjust the spices as you see fit. I think the mustard and celery seed are crucial.
