Why it works: Pepper and celery match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into soft ribbons in the hot broth, giving the soup body and a light texture.
- Flour
- Thickens the broth slightly so the soup feels fuller in the mouth.
- Milk
- Adds richness and softens the egg and flour mixture before it meets the hot broth.
- Chicken or veal broth
- Forms the savory base that carries all the other flavors.
The step that matters
Stir the egg mixture into the boiling broth. Eggs can scramble into lumps if added to liquid that is too cold or left to boil too hard. Keeping the broth at a steady simmer while stirring in the mixture helps it set into fine, even strands.
Swap the celery
The recipe marks celery as optional. How well each one fits the dish's main ingredients (chicken, egg, flour, milk, pepper):
- Nutmegfits better
- Turmericfits better
- Cardamomfits better
- Celerythe original
Fit is the average pairing score against chicken, egg, flour, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
“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.
