Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Dried green peas
Provide the main body and starch that thicken the soup as they break down.
Gelatine
Sets the broth so it firms up as it cools, giving the soup a jellied texture.
Onion
Adds savoury depth and aroma to the broth as it simmers.
Carrot
Adds gentle sweetness and colour to the broth as it simmers.

The step that matters

Strain the mixture, allowing only a little pulp in the broth. Straining controls the texture: too much pulp makes the soup grainy and cloudy, while too little removes the body the peas give. Keeping a small amount of pulp balances smoothness with substance.

Swap the parsley

The recipe marks parsley as optional. How well each one fits the dish's main ingredients (peas, onion, carrot, celery, almond, butter, walnut):

  1. Parsleythe original
  2. Tarragonfits about as well
  3. Thymefits less well
  4. Cardamomfits less well

Fit is the average pairing score against peas, onion, carrot, celery, almond, butter, walnut. Candidates are from the same food group and used in at least 100 recipes.
