Ingredients
Directions
Make the soup
Place the marrow bone and split peas in a soup pot.
Cover with 3 quarts of water and simmer slowly for 3 hours.
Season with pepper and coarse sea salt to taste.
Strain the soup through a fine sieve, mashing and pressing the peas back into the soup. Stir well to combine.
Serve
Place cube-shaped pieces of buttered toast in the bottom of a tureen.
Pour the hot soup over the toast and serve.

What each ingredient does
- Split peas
- Break down during long simmering to thicken the soup and give it body.
- Marrow bone
- Slowly releases fat and flavor into the water, giving the soup richness.
- Buttered toast
- Soaks up the hot broth at the bottom of the tureen, adding softness and fat.
The step that matters
Simmer slowly for 3 hours. A gentle simmer lets the peas soften fully and the bone release its flavor without the liquid reducing too fast or the peas scorching on the bottom of the pot. Too vigorous a boil can break the soup unevenly.
