To Soak or Not to Soak
Some people wouldn't dream of making split pea soup without soaking the peas in water overnight first. Overnight soaking does help to shorten the cooking time of the peas, but it's not a necessary part of the process. Unsoaked peas will take from 1 to 2 hours of simmering, and soaked peas will take 40 to 60 minutes. Split peas absorb lots of water as they cook, so check the soup often and add liquid as needed. The peas only need to be cooked until they are tender, but if you like a smoother, creamier texture, cook them longer until they soften and fall apart. If you like really silky soup, take the extra step of pureeing the peas once they have softened. This is a great job for your immersion blender if you have one, but you can also do it in batches in your regular countertop blender .
Fill 'er Up
Ham, bacon and sausage all go exceptionally well with peas. One of the most traditional ways of making split pea soup is to flavor it with ham bones. To this favorite combination most people add onion, celery, potatoes and carrots. In the herb department, bay leaves, thyme, mint, marjoram and parsley are all delicious enhancements to a pot of pea soup. If you like to flavor your soup with tomatoes, lemon juice, vinegar, wine or any other acidic ingredients, wait until the end of cooking to add these, or else the acid will prevent the uncooked split peas from ever getting soft.
Finishing Touches
When the peas are soft and the veggies are cooked, stir in your favorite seasonings and keep on tasting until it's just right. We like to use salt, freshly cracked black pepper, nutmeg and lemon juice. Ladle the piping hot soup into big bowls and garnish with a dollop of sour cream or plain yogurt, some minced fresh parsley or mint, and a few crispy croutons. Now hunker down and savor each bite of that wonderful soup!
