Why it works: Carrot and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 10,172 recipes mention both. Both carry myristicin, which smells spice, warm. The science ↓
The recipe
Ingredients
Contains: wheat, soy (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the base
Chop the onion, carrots and celery.
Sauté them in the olive oil or water, stirring frequently, until the onion starts to soften.
Add the split peas and mix well.
Simmer the soup
Add the water or stock and soy sauce, and bring to a boil.
Simmer over low heat for 1 hour or until the peas are soft.
Thicken and serve
Dissolve the arrowroot or tapioca flour in a bit of cold water.
Stir the mixture into the hot soup.
Add the salt and pepper to the soup, stir, and serve.
Add ground cumin, curry powder, or cayenne pepper, 1/2 tsp at a time, to make a spicier version.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Split peas
- Form the body of the soup as they soften and break down during simmering.
- Arrowroot or tapioca flour
- Thickens the soup as its starch gelatinizes in the hot liquid.
- Extra virgin olive oil
- Carries flavour and softens the onion, carrots and celery at the start.
- Soy sauce
- Adds savoury depth, saltiness and colour to the broth.
The step that matters
Stir the arrowroot or tapioca slurry into the hot soup. Starch must be dissolved in cold water first, otherwise it clumps. Stirred into hot liquid, it swells and thickens evenly rather than forming lumps.
Flavor stand-ins for the arrowroot
How well each one fits the dish's main ingredients (olive, onion, carrot, celery, peas, sauce, pepper):
- Tomatobetter flavor fit
- Capsicumbetter flavor fit
- Potatobetter flavor fit
- Arrowrootthe original
Fit is the average pairing score against olive, onion, carrot, celery, peas, sauce, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
