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

What each ingredient does

Calf's head liquor
Forms the rich, gelatin-bearing base that gives the soup its body and flavor.
Meat extract
Adds concentrated savory depth and deepens the soup's color.
Corn flour or arrowroot
Thickens the strained liquid to a creamy, lightly viscous texture.
Sherry
Adds aromatic acidity and warmth that brightens the rich broth.
Lemon juice
Adds acidity that balances the richness and sweetness of the soup.
Gelatinous calf's head parts
Contribute chewy texture and additional body to the finished soup.

The step that matters

Thicken to the consistency of very thin cream. Starch thickeners must be heated to swell and gelatinize before they reach full thickening power. Adding too little or stopping too early leaves the soup thin, while overheating can break down the starch and thin it again.

Swap the onion

How well each one fits the dish's main ingredients (clove, thyme, marjoram, parsley, meat, corn, lemon):

  1. Carrotfits better
  2. Shallotfits better
  3. Parsnipfits better
  4. Onionthe original

Fit is the average pairing score against clove, thyme, marjoram, parsley, meat, corn, lemon. Candidates are from the same food group and used in at least 100 recipes.
