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 peas and place them in a large soup pot with the brown gravy stock.
Boil gently for 30 minutes.
In a skillet, fry the sliced onions, carrots, and turnips in butter until browned.
Add the fried vegetables to the soup.
Simmer until the peas are reduced to a pulp.
Strain and season
Season with salt and cayenne.
Boil for 2-3 minutes.
Pass the soup through a sieve, pressing the vegetables through.
Combine the strained soup with additional stock if too thick, or reduce by boiling if too thin.
Finish and serve
Add the sliced celery.
Cook until tender.
Mix curry powder with a few spoonfuls of soup. Stir it in before serving.
Serve the soup hot with small fried sippets on the side.

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 thicken the soup and give it body.
- Butter
- Fat for frying the vegetables, adding richness and browning them for flavor.
- Onions
- Browned in butter, they add sweetness and savory depth to the base.
- Carrots
- Add sweetness and body once cooked and pressed through the sieve.
- Turnips
- Contribute mild sweetness and body to the pureed soup.
- Celery
- Adds a fresh, aromatic vegetable note and softens to a tender texture.
The step that matters
Pressing the soup through a sieve. The soup must be pushed through with the vegetables to give a smooth, thick texture. Skipping this leaves the soup grainy and thin, since the peas and vegetables hold most of the body.
