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

What each ingredient does

Calf's feet
Their collagen breaks down during long boiling into gelatin, giving the broth body and a slight set when cold.
Wine
Adds acidity and aromatic depth that balance the rich, mild flavour of the broth.
Soy sauce
Adds savoury, salty depth and a deeper colour to the finished broth.

The step that matters

Boil for 2 to 3 hours, adding more water if it boils away. Long, gentle simmering is what converts the collagen in the feet into gelatin. If the pot boils dry, the broth becomes concentrated and the gelatin and flavour are uneven, so topping up water keeps the liquid volume steady.

Swap the mace

How well each one fits the dish's main ingredients (onion, carrot, wine, sauce):

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

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