Why it works: Onion and carrot are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 21,601 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the soup, carrying all the other flavors and textures.
- Butter and flour
- Form a roux that thickens the milk into a smooth, body-rich soup.
- Grated cheese
- Melts into the base to supply the cheese flavor and a creamy richness.
- Egg yolks
- Enrich and thicken the soup, adding richness and smoothness when cooked gently.
The step that matters
Adding the egg yolks. Egg yolks thicken by gentle heat; if the soup is too hot when they go in, they can scramble and turn grainy. Keep the heat low and cook only briefly.
Swap the white pepper
How well each one fits the dish's main ingredients (milk, mace, onion, carrot, butter, flour, cheese):
- Nutmegfits better
- Parsleyfits better
- Thymefits better
- White pepperthe original
Fit is the average pairing score against milk, mace, onion, carrot, butter, flour, cheese. Candidates are from the same food group and used in at least 100 recipes.
