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

What each ingredient does

Vegetable marrow
Forms the bulk of the soup and breaks down into a smooth, thick base when stewed and sieved.
Boiling cream
Adds richness and a silky body to the soup.
Yolk of egg
Thickens the soup slightly and adds richness when added near the end of cooking.
Veal or fowl broth
Provides the liquid for stewing and a savoury meat-based flavour.

The step that matters

Add the cream and yolk when nearly cooked. Egg yolk thickens when heated but can curdle if it boils. Adding the boiling cream and yolk near the end, with the soup no longer at a hard boil, keeps the texture smooth and glossy.

Swap the cocoa
