In a large pot, add peas and 6 cups boiling water; cover the pot and let soak for 1 hour.
Then drain the water and add 6 cups of fresh water and remainder of ingredients.
Bring to a boil and then lower the heat and simmer until peas are thoroughly cooked and tender (about 45 minutes, depending on how old the peas are).
Add water during cooking time because split peas absorb water while cooking.
Notes / Tips / Wine Advice:
You can make split pea soup (using this recipe) without soaking the peas first, but the soup will take longer to cook until the peas are tender—about 2 hours.
