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

What each ingredient does

Tapioca
Thickens the soup as it cooks, turning it clear and giving it body.
Egg yolk
Enriches the soup and adds richness and body when combined with the cream.
Cream
Adds richness and a smooth, silky texture to the finished soup.
Butter
Adds fat for richness and a rounded flavor to the finished soup.

The step that matters

Slowly pour the soup into the tureen, stirring constantly. Pouring hot soup too quickly into the beaten egg yolk can scramble it, causing curdling. Adding the hot liquid gradually while stirring gently warms the yolk so it blends smoothly into the soup.
