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 ↓
Simple Method of Making Barley Broth
Ingredients
Directions
Prepare the barley broth
Wash the barley in cold water.
Add the barley and sliced onions to 5 quarts of water.
Boil gently for 1 hour.
Pour the boiled mixture into a pan.
Make the soup
In a saucepan, melt the dripping or fat bacon.
Stir in the oatmeal and rub together until it forms a paste.
Gradually add the barley broth by spoonfuls.
Stir until the mixture boils.
Mix the spices in a teacup.
Add a little of the spice mixture to the soup.
Pour the rest of the spice mixture into the soup.
Simmer for 15 minutes.
Add salt to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Scotch barley
- Releases starch as it simmers, thickening the broth and giving it body.
- Oatmeal
- Forms a paste with the melted fat that is then thinned into the broth, adding thickness.
- Beef or mutton dripping
- Carries flavour and richness, and helps the oatmeal form a smooth paste.
- Sliced onions
- Adds savoury sweetness and aroma to the broth as it boils.
The step that matters
Adding the oatmeal paste to the broth. Adding the broth to the oatmeal paste slowly, by spoonfuls, keeps the starch smooth. Dumping it in at once can form lumps that are hard to break up.
Swap the onion
How well each one fits the dish's main ingredients (barley, beef, celery, pepper):
- Carrotfits 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.
