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

What each ingredient does

Celery
Provides the main flavour and, once puréed, the body of the soup.
Onion
Adds savoury sweetness and aroma as it softens in the cooking water.
Stock
Supplies the savoury liquid that thins the purée to a soup.
Egg yolks
Thicken and enrich the soup as their proteins set with gentle heat.
Cream or milk
Adds richness and a smooth, velvety mouthfeel.

The step that matters

Stir in the egg yolks just before serving. Egg yolk proteins thicken the soup by setting with gentle heat. If the soup is kept at a rolling boil after the yolks go in, the proteins overcook and curdle, leaving the texture grainy instead of smooth.

Swap the onion

How well each one fits the dish's main ingredients (celery, lemon, egg, cream):

Fit is the average pairing score against celery, lemon, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
