Why it works: Egg and white pepper are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 2,312 recipes. Both carry 2-methylbutyraldehyde, which smells malty, chocolate. The science ↓

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.
