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

What each ingredient does

Chestnuts
Form the body of the soup, thickening it into a smooth puree when sieved.
Stock
Provides the liquid base and carries the flavour of the soup.
Cream
Adds richness and a smoother, silkier mouthfeel to the finished soup.
Egg yolk
Enriches and thickens the soup gently when stirred in with milk.

The step that matters

Add the egg yolk and milk without boiling. Egg yolk thickens by gentle heat; if the soup boils after the yolk is added, the egg can scramble and curdle, leaving the texture grainy.

Swap the chestnut
