Rinse split peas and soak in a pan of water for at least an hour or up to 8 hours to plump them up. (lots of people skip this step but it's how my mother taught me to make this soup.)In a large heavy bottomed pan heat the oil and add the garlic, onion and carrots and slowly cook without burning or coloring.Add the split peas, chicken stock, bones, cracked pepper and bouquet garni and simmer for 1½ hours.Remove bouquet garni and discard - it's done its workRemove the bones and pick off the meat (it should just fall apart) and return to soup pot.Taste and adjust seasoning.Either blitz or blend if you want smooth soupStir in creamServe with some nice crusty bread
