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

What each ingredient does

Bones
Release collagen and flavour into the water, giving the broth body and richness.
Potatoes
Their starch thickens the broth when mashed into it.
Carrot
Adds sweetness and aroma to the broth as it simmers.
Turnips
Add earthy flavour and aroma to the broth as it simmers.

The step that matters

Mash the reserved potatoes into the soup. As potatoes break down, their starch dissolves into the hot liquid and thickens it. Mashing them in while the soup is hot lets the starch distribute evenly, giving a smooth, body-rich texture instead of lumps.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (meat, carrot, turnip, potato, pepper):

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

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