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
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 onions, carrots, and turnips in butter until browned.
Add the fried vegetables to the soup and simmer until the peas are reduced to pulp.
Season with salt and cayenne, then boil for 2-3 minutes.
Strain and finish
Pass the soup through a sieve, pressing the vegetables through.
In a clean saucepan, combine the strained soup with additional stock if too thick, or reduce by boiling if too thin.
Add the sliced celery and cook until tender.
For added flavor, mix curry powder with a few spoons of soup and 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 pulp to thicken the soup and give it body.
- Brown gravy stock
- Provides the liquid base and savory flavor for the soup.
- Onions
- Browned in butter to add sweetness and savory depth.
- Carrots
- Browned with onions and pressed through to add sweetness and body.
- Turnips
- Browned with the other vegetables and pressed through to add body and flavor.
- Celery
- Cooked until tender to add aroma and mild savory flavor.
The step that matters
Pressing the soup through a sieve. Pressing the cooked peas and vegetables through a sieve breaks them into a smooth pulp that thickens the soup. Skipping or rushing this step leaves the soup grainy and thin.
