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

What each ingredient does

Veal knuckle
Provides rich meat and gelatin that give the soup body and savoury depth.
Cow heels
Release gelatin during long cooking, adding body and a silky mouthfeel to the soup.
Madeira wine
Adds aromatic sweetness and depth that rounds out the savoury broth.
Yolks of eggs
Thicken the soup and add richness through their emulsifying proteins and fat.
Lemon juice
Adds acidity that brightens the rich broth and balances its fattiness.

The step that matters

Thicken with yolks of eggs. Egg yolks thicken when heated gently, but above about 70°C they can curdle or scramble. Add them off the boil, with some hot liquid whisked in first, to keep the soup smooth.

Swap the mace
