Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Provides the meat and gelatin that give the soup its body and rich texture.
- Butter
- Fat that carries the onion and herbs and begins the base of the soup.
- Flour
- Thickens the broth slightly so it has a smoother body.
- Madeira or sherry
- Adds acidity and a rich, fortified wine aroma to the finished soup.
- Lemon juice
- Adds acidity that brightens the flavour of the rich broth.
- Lean ham
- Adds savoury, salty depth to the broth.
The step that matters
Dredge in a small quantity of flour. Flour stirred into hot fat and cooked briefly thickens liquid smoothly; adding it straight to liquid or using too much can leave lumps or a pasty texture.
Swap the onion
How well each one fits the dish's main ingredients (ham, parsley, butter, flour, sherry, pepper, lemon):
- Shallotfits better
- Carrotfits better
