Rinse and sort the beans, discarding any broken or rotten beans or rocks.
Place the beans in the slow cooker crock. Add spices and water. Cook on high for 8 hours. If it appears that too much water is evaporating, turn the heat down.
When the beans are done, strain the juice from the beans and reserve.
With a potato masher smash the beans, adding in reserved liquid. Add additional seasonings as desired.
