Why it works: Parsley and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Cream of Barley Soup
Ingredients
Directions
Make the base
Fry the onion in butter until lightly browned.
Add flour to the onion and mix to color it.
Pour in hot water or veal broth, and season with salt, pepper, parsley, celery, and allspice.
Simmer the stock
In a separate saucepan, add the veal and bone to 3 quarts of water, along with mutton trimmings if using.
Bring to a boil, then add the contents of the frying pan.
Simmer for 4 hours, skimming off any scum, then strain the soup.
Finish the soup
Wash and boil the barley, then rub it through a sieve and add to the strained soup.
Whisk in the hot cream and keep warm until serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal knuckle
- Gives the broth its body and rich meaty flavor as it simmers for hours.
- Barley
- Thickens the soup as it breaks down when rubbed through a sieve.
- Butter
- Carries the onion's flavor and helps it brown lightly at the start.
- Flour
- Browns with the onion and helps lightly thicken the base.
- Rich cream
- Adds richness and a smooth, silky texture when whisked in.
The step that matters
Whisk in the hot cream and keep warm. Cream can curdle or separate if it boils or overheats, so it should be added hot but not brought to a boil and kept gently warm.
Swap the onion
How well each one fits the dish's main ingredients (veal, butter, flour, pepper, parsley, celery, allspice):

- Onionthe original
Fit is the average pairing score against veal, butter, flour, pepper, parsley, celery, allspice. Candidates are from the same food group and used in at least 100 recipes.
