Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the soup as it cooks with the barley and butter.
- Pearl barley
- Provides body and a chewy texture as it simmers in the broth.
- Butter
- Adds richness and fat, carrying flavour through the soup.
- Egg yolks
- Enrich and thicken the cream, giving the finished soup a smooth, velvety texture.
- Cream
- Adds richness and a silky mouthfeel to the finished soup.
The step that matters
Stirring the cream and egg yolks into the soup. Egg yolks can curdle if they get too hot. Strain the mixture and keep it warm rather than boiling, so the yolks thicken gently into a smooth finish.
