Why it works: Carrot and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,173 recipes. Both carry myristicin, which smells spice, warm. The science ↓
Rich Peas Soup
Ingredients
Directions
Prepare the soup base
Drain the soaked split peas and place them in a large soup pot with the brown gravy stock.
Boil gently for 30 minutes.
In a separate pan, fry the onions, carrots, and turnips in butter until tender.
Add the fried vegetables to the soup and simmer until the peas are reduced to a pulp.
Season and strain
Season with salt and cayenne pepper, then boil for 2-3 minutes.
Pass the soup through a sieve, pressing the vegetables to extract flavor.
Return the strained soup to a clean saucepan, adding fresh stock if too thick.
Boil quickly to reduce if too thin, then stir in the sliced celery.
Serve
Serve the soup hot with small fried sippets on the side.
For added flavor, mix curry powder with a few spoonfuls of soup and add it back when the soup begins to boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yellow split peas
- Break down into a pulp to give the soup its thick body.
- Brown gravy stock
- Forms the liquid base and carries the flavor of the soup.
- Onions
- Fried in butter until soft, adding sweetness and savory depth.
- Carrots
- Add natural sweetness and body when cooked and pressed through the sieve.
- Turnips
- Soften during frying and add earthy flavor and body to the soup.
- Butter
- Fat that carries the flavor of the frying vegetables into the soup.
The step that matters
Simmering the peas until they break down to a pulp. Split peas must cook long enough to soften fully and release starch, which thickens the soup. Undercooked peas leave the texture grainy and the soup thin.
