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

What each ingredient does

Potatoes
Break down when mashed to thicken the soup and give it body.
Egg yolks
Enrich the soup and add richness and a smooth, velvety texture.
Cream
Adds fat for richness and a smoother mouthfeel to the soup.
Turnips
Add mild sweetness and earthy flavor to the broth as it simmers.
Mutton
Releases gelatin and savory flavor into the broth during long simmering.

The step that matters

Stir the beaten yolks and cream into the soup. Egg yolks can curdle if they get too hot. Warm the soup gently and add the yolk mixture slowly, off the boil, so it thickens smoothly rather than scrambling.

Swap the onion
