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 ↓
Dr. Kitchiner's Receipt to Make Barley Broth
Ingredients
Directions
Make the broth
Combine washed barley, sliced onion, and water in a large pot and boil gently for 1 hour.
Pour the mixture into a pan and return it to the saucepan.
Thicken and season
Add the drippings, suet, or minced bacon to the saucepan and melt over low heat.
Stir in the oatmeal until it forms a paste, ensuring the fat combines with the broth.
Gradually add the barley broth, stirring well until it boils.
In a cup, mix celery or cress seed and cayenne (or pepper) with a little soup, then pour it back into the pot.
Simmer gently for an additional 15 minutes, then season with salt before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Scotch barley
- Releases starch and body as it simmers, giving the broth its substance.
- Oatmeal
- Forms a paste with the melted fat and thickens the broth further.
- Drippings, suet, or bacon fat
- Adds richness and carries flavour through the broth.
The step that matters
Stirring the oatmeal into the melted fat. Oatmeal must be worked into the fat to form a smooth paste before liquid is added. If it is added to hot liquid without this, it clumps and thickens unevenly, leaving lumps that do not disperse.
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.
