My favorite split pea soup starts with a "New England Boiled Dinner" with a smoked shoulder. When the dinner is done done, the sandwiches are gone and there is still some meat on the ham bone it goes in the crock pot with water and dry split peas. I do this in the morning and it simmers all day. A few peeled carrots are added, cut like you were sharpening a stick, garlick powder (one of the few places I use it) some Tobasco and salt and pepper to taste. Once the ham bone has been removed and the meat readded, it's ready. I'll bring a thermos to work every day until it's gone. It's really quite smooth. I always remember the chant of the early settlers lamenting a lack of varity in their diet: "Pea porridge hot, pea porridge cold, pea porridge in the pot, nine days old." I'll bet they never thought we'd strive to keep it alive!
