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

What each ingredient does

Marrow
Melts into the dumplings, adding richness and a savoury, meaty flavour.
Egg
Binds the mixture together so the balls hold their shape in the soup.
Biscuit or roll
Soaked in milk and added to soften the mixture, giving it a tender dumpling texture.

The step that matters

Mixing to a dumpling consistency. Too much liquid makes the balls fall apart in the soup, while too little leaves them dense and dry. Adding the soaked bread gradually lets you judge the texture by eye and feel.

Swap the parsley

How well each one fits the dish's main ingredients (egg, nutmeg, biscuit):

  1. Cinnamonfits better
  2. Capersfits better
  3. Allspicefits about as well
  4. Parsleythe original

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