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

What each ingredient does

Egg
Binds the flour into a dough that holds together when rolled.
Flour
Forms the gluten network that gives the dough its structure and chew.
Potatoes
Their starch softens during cooking and lightly thickens the soup.
Onion
Releases sweetness and savoury aroma as it cooks in the broth.

The step that matters

Dry the dough before rolling it up and slicing. A dough that is still moist sticks to itself and the board and tears when rolled. Drying firms the surface so the strips keep their shape and separate cleanly.

Swap the onion

How well each one fits the dish's main ingredients (potato, turnip, parsnip, pepper, parsley, egg, flour):

  1. Leekfits better
  2. Carrotfits better
  3. Beetrootfits better
  4. Onionthe original

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