Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

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

Fit is the average pairing score against meat, ham, celery, parsley, potato, turnip, pepper. Candidates are from the same food group and used in at least 100 recipes.
