This is a wonderful recipe for yellow pea soup. You can use about 1/2 pound salt pork, rinsed if covered with salt in place of the smoked ham bone. Just a tip, don't throw away the bone from your cooked ham, wrap tightly in foil and freeze, it is wonderful to use in pea soups, make certain to leave some meat on the bone to shred into the soup. If you have any dried savory, then add in about 1/2 teaspoon to the soup along with the chives. I sometimes add in a couple of potatoes that are cut into small cubes into the soup the last hour of cooking, but that is optional. This soup will take around 2-3 hours to cook.
