Why it works: Celery and pepper 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 stock
Prepare the stock by cutting up the onion and adding it to a large pot with the meat and celery seed or salt.
Boil the mixture for 2-3 hours for chicken or 5-6 hours for veal.
Strain carefully and remove all fat.
Reheat the strained stock for 30 minutes before serving.
Thicken and finish the soup
Season the soup with salt, pepper, and mace to taste.
Cream the butter in a separate bowl and mix in the flour or corn-starch.
Heat the cream in a saucepan until boiling.
Gradually add the boiling cream to the butter and flour mixture while stirring.
Beat the egg yolks and stir them into the butter, flour, and cream mixture.
Pour the mixture into the boiling soup and stir for 5 minutes before serving.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Meat
- Gives the stock its body and savory flavor as it simmers for hours.
- Butter
- Adds richness and, with the flour, forms a smooth base that thickens the soup.
- Flour
- Thickens the soup when cooked with butter and cream, giving it body.
- Cream
- Adds richness and a smooth, velvety texture to the finished soup.
- Egg yolks
- Enrich and thicken the soup, adding body and a silky texture.
The step that matters
Adding the egg yolk mixture to the boiling soup. Egg yolks can curdle if they get too hot too fast. Stirring the mixture gradually with hot liquid and keeping the soup from boiling hard helps it stay smooth and thickened.
Swap the mace
How well each one fits the dish's main ingredients (meat, onion, celery, pepper, butter, flour, cream):
- Parsleyfits better
- Thymefits better
- Turmericfits better
- Macethe original
Fit is the average pairing score against meat, onion, celery, pepper, butter, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
