2 quarts water
1 pound green split peas
1 carrot, diced
1 medium onion, diced
1 medium stalk celery, diced
1 bay leaf
1/4 teaspoon thyme
1 teaspoon salt
1 dash pepper
1 pinch cayenne pepper

If desired, a ham bone and a small amount of cut-up ham can be added to this soup.

Put all ingredients in a large soup pot. Bring to a boil, and boil 15 minutes. Simmer, covered, until the peas are soft. If you do not add ham and wish a smooth soup, you may put small quantities in the blender and blend it to the texture you desire. This soup freezes well.
