Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
White Soup
Ingredients
Directions
Make the broth
Place the veal in a soup kettle and cover it with cold water.
Bring to a boil and skim thoroughly.
Simmer, covered, for 2 hours.
Strain the broth and add salt, pepper, mace, and vermicelli.
Boil slowly for about 15 minutes until the vermicelli is tender.
Finish and serve
Remove from heat and stir in the butter.
In a tureen, beat the egg yolks with the cream.
Slowly pour the hot soup over the egg mixture, stirring quickly.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal knuckle
- Releases gelatin and flavour into the broth as it simmers, giving body to the soup.
- Vermicelli
- Thin pasta that softens in the hot broth and gives the soup its body.
- Egg yolks
- Thicken the cream and enrich the soup when stirred into the hot broth.
- Cream
- Adds richness and softness, and mellows the egg yolks when combined with them.
- Butter
- Adds fat and a rounded richness to the finished soup.
The step that matters
Slowly pour the hot soup over the egg mixture, stirring quickly.. Adding hot broth to the yolks too fast or without stirring can scramble the eggs into lumps. Tempering gradually and stirring keeps the mixture smooth and creamy.
Swap the mace
How well each one fits the dish's main ingredients (veal, pepper, butter, cream, egg):
- Nutmegfits better
- Parsleyfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against veal, pepper, butter, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
