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 ↓
White Soup
Ingredients
Directions
Make the soup
Beat the eggs, flour, and milk together.
Pour the mixture slowly through a sieve into boiling soup, adding salt and pepper.
In a separate pot, combine boiled rice and 2 quarts of boiling milk with chopped celery.
Cover and simmer over boiling water until the celery is tender, then season to taste.
Serve
In a tureen, place the well-beaten eggs.
Pour the soup over the eggs and top with crisp bread dice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the soup as they set in the hot liquid, giving it body.
- Flour
- Stabilises the egg mixture and helps thicken the soup smoothly.
- Milk
- Forms the creamy liquid base and adds richness to the soup.
- Rice
- Adds body and a soft texture to the soup.
- Celery
- Contributes savoury, aromatic flavour as it softens in the milk.
The step that matters
Pour the egg mixture slowly through a sieve into the boiling soup. Eggs can scramble and flour can clump if the mixture hits the hot liquid too fast. A slow pour through a sieve breaks up lumps and lets the eggs thicken the soup evenly.
Swap the celery
How well each one fits the dish's main ingredients (egg, flour, milk, pepper, rice, bread):
- Nutmegfits better
- Cinnamonfits better
- Turmericfits better
- Celerythe original
Fit is the average pairing score against egg, flour, milk, pepper, rice, bread. Candidates are from the same food group and used in at least 100 recipes.
