1. SOAK BEANS: Put beans in a pot with 4 cups of water and bring to a boil. Boil 2 minutes, then cover, remove from heat, and let sit for an hour. (You can also put the beans in a bowl or pot and cover them with water at least 2 inches above the beans, and let them sit overnight.) Drain and rinse.
2. LOAD SLOWCOOKER with beans and the ham shank. Add the
rest of the ingredients except salt. Do not salt soup until cooking is done, since the ham hock is already salty. Use your judgment with thyme,
parsley and pepper. You may substitute fresh herbs if available, as minced leaves. Be careful not to use too
much red pepper. If you don't like chunks of carrot and celery, put
them in whole and remove when soup is done; otherwise, you can dice
them into the soup.
3. COOK on High for 4-5 hours, or on Low for 8-9 hours, until ham falls off the bone.
4. Remove bay leaves, bones and any visible pieces of gristle with a slotted spoon. Pull out
the big ham chunks and shred them with two forks, then put back in.
If soup is not thick, allow to cook for another hour with lid off, to
reduce the water content. Salt only after cooking is complete - the
ham hock is already salty (and so is the stock if you use canned).
