Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 8,053 recipes mention both. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Vermicelli Soup
Ingredients
Directions
Make the stock
Make 4 quarts of good stock with carrot, turnip, onions, parsley roots, mace, salt, and white pepper.
Strain the stock and remove all the fat.
Thicken the soup
Boil the crumb of 3 French rolls in some of the stock until soft enough to mash smooth.
Add the mashed rolls to the boiling soup and stir well.
Boil for 15 minutes.
Mix 2 beaten egg yolks with 3 tablespoons of cream and add to the soup.
Cook the vermicelli and serve
Boil 2-3 ounces of vermicelli in water for 15-20 minutes, then strain.
Place the vermicelli in a tureen and pour the soup over it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- French rolls
- Soften and mash to thicken the soup body.
- Egg yolks
- Enrich the soup and thicken it slightly when added off the boil.
- Cream
- Adds richness and a silky mouthfeel to the soup.
- Vermicelli
- Provides the noodle texture that the soup is served over.
The step that matters
Adding the egg yolks and cream. If the soup is kept at a hard boil after the egg yolks go in, the proteins in the yolks can scramble and curdle, leaving the soup grainy. Stirring the yolk and cream mixture in gently keeps the soup smooth.

Fit is the average pairing score against carrot, turnip, onion, parsley, mace, egg, cream. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
