Why it works: Celery and parsley 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 ↓
Barley Broth
Ingredients
Directions
Prepare
Break the bones into splinters and chop the meat.
Mince the vegetables and put all into a soup kettle with the water.
Make the broth
Boil slowly for three hours until the liquid has reduced by one-third.
Meanwhile, wash the barley and boil it in salted water for half an hour.
Strain the soup and cool it to let the fat rise, then remove the fat.
Finish and serve
Season the soup with salt and pepper, then bring it to a boil.
Skim the soup, add the barley, and cook gently for another half hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Knuckle of veal
- Releases gelatin and savory flavor into the broth, giving body as it simmers.
- Scotch barley
- Thickens the broth and adds a chewy texture as its starch softens during cooking.
- Onion
- Adds aromatic sweetness and depth as it softens and cooks into the broth.
- Turnip
- Contributes mild sweetness and earthy flavor to the broth as it cooks.
- Celery
- Adds aromatic, savory flavor to the broth as it simmers.
The step that matters
Cooling and removing the fat after straining. Fat floats and solidifies as the broth cools, so it can be lifted off cleanly. Skimming before cooling leaves greasy broth, while skipping the removal leaves an oily texture.
