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 ↓
Barley Broth
Ingredients
Directions
Make the broth
Combine the Scotch barley, sliced onions, and 5 quarts of water in a large pot.
Boil gently for 1 hour, then pour the broth into a pan.
Season and finish
Melt the beef or mutton drippings in the same saucepan.
Gradually stir the melted fat into the barley broth, mixing well.
In a teacup, combine celery or aniseed with cayenne or pepper and a small amount of the soup.
Pour this mixture into the broth and stir thoroughly.
Simmer gently for an additional 15 minutes.
Season with salt to taste before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Scotch barley
- Thickens the broth and gives it a chewy, hearty body as it cooks.
- Beef or mutton drippings
- Adds fat for richness and mouthfeel, carrying flavor through the broth.
- Sliced onions
- Contribute savory sweetness and aromatic depth to the broth.
The step that matters
Stirring the melted fat into the broth. Fat added to hot liquid can separate or float in globules if not stirred in gradually and thoroughly. Mixing the fat in slowly helps it emulsify and spread evenly, so the broth tastes uniformly rich.
Swap the onion
How well each one fits the dish's main ingredients (barley, beef, celery, pepper):
- Carrotfits better
- Leekfits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against barley, beef, celery, pepper. Candidates are from the same food group and used in at least 100 recipes.
