Highly rated split pea soup and ham bone recipes from Food.com and AllRecipes.com begin by placing two cups of dried split peas into a large pot filled with water. Boil the water and then remove the pot from the heat and allow it to sit for one hour.
Bring the pot of peas to a boil once again over medium heat and add in one large ham bone, two large diced carrots, two chopped onions, two chopped celery stalks, one bay leaf, two beef bullion cubes, one teaspoon of salt, 1/4 teaspoon of crushed peppercorns and a pinch of thyme. Let the mixture simmer for 1 1/2 hours and then remove the ham bone. Make sure to pull off any cooked ham from the bone and add it back into the soup.
Another option is to saute one cup of chopped onion in the pot prior to adding the green peas and water. Add in the dried split peas and ham bone after the onions have become translucent. Cover the ingredients with water and season them with salt and pepper. Cook the ingredients for two hours until most of the water has evaporated and then remove the pot from the heat and allow it to thicken.
