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

What each ingredient does

Bones
Release gelatin and flavour into the water during long, gentle simmering, giving body to the broth.
Thickening agent
Starch or gelling material that thickens the broth when added at the end.

The step that matters

Skim after the water comes to a boil. Foam and fine impurities rise from the bones as the water heats. Removing them early keeps the broth clear and prevents a murky, off-flavoured result.

Swap the mace

How well each one fits the dish's main ingredients (carrot, onion, parsnip, turnip, allspice, rice):

  1. Thymefits better
  2. Parsleyfits better
  3. Celeryfits better
  4. Macethe original

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