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

What each ingredient does

Egg whites and shells
Whites coagulate as they heat, trapping suspended particles so the stock clears.
Lean beef
Chopped lean meat adds savoury flavour and body and helps bind impurities into the clarifying raft.
Brown stock
Forms the liquid base that carries the flavour of the finished soup.
Onion and carrot
Vegetables add sweetness and aromatic depth to the stock during simmering.

The step that matters

Bringing the soup to a gentle simmer. If the mixture boils hard or is stirred once the egg whites begin to set, the raft breaks apart and cloudiness returns. Gentle heat lets the whites form a raft that traps particles, leaving the soup clear when strained.

Swap the onion

How well each one fits the dish's main ingredients (beef, egg, carrot, celery, allspice, clove):

  1. Parsnipfits better
  2. Leekfits better
  3. Turnipfits better
  4. Onionthe original

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