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

What each ingredient does

Carrots
Supply the main flavour, sweetness, and the pulp that thickens the soup.
Onions
Add savoury sweetness and aromatic depth to the broth.
Turnip
Adds mild sweetness and body to the stewed broth.
Broth
Forms the liquid base that carries the flavour of the soup.

The step that matters

Rubbing the carrots through the sieve. Carrots must be stewed until soft enough to pulp; if they are underdone, they will not pass smoothly through the sieve and the soup will turn out grainy. Pressing the pulp through also removes fibrous bits so the soup thickens evenly when boiled.

Swap the onion

How well each one fits the dish's main ingredients (turnip, pepper, mutton, carrot):

  4. Onionthe original

Fit is the average pairing score against turnip, pepper, mutton, carrot. Candidates are from the same food group and used in at least 100 recipes.
