Why it works: Barley and turnip match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 629 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Barley Broth
Ingredients
Directions
Prepare the broth
Wash the barley well in cold water.
In a stewpan, combine the beef, barley, and cold water.
Set over low heat and bring to a boil, skimming off any scum.
Add the onion, turnip, celery, white pepper, and salt.
Cover and let simmer slowly for 4 hours, stirring occasionally.
Finish and serve
Remove the meat and keep it warm.
Skim the fat from the broth and pour it into a tureen.
For the sauce, thicken ½ pint of broth with the flour, cayenne pepper, and ketchup in a saucepan.
Simmer gently, stirring until it boils, then pour over the meat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Scotch barley
- Swells during long simmering, thickening the broth and giving it body.
- Leg of beef
- Slow simmering breaks down connective tissue, enriching the broth and making the meat tender.
- Ready-browned flour
- Thickens the sauce when it boils, giving it a smooth, glossy body.
- Ketchup
- Adds tomato sweetness and acidity to the thickened sauce.
The step that matters
Simmer the sauce until it boils. Flour only thickens fully once it reaches a boil, so the sauce must be stirred and brought to a boil before it is poured over the meat. Stirring prevents lumps from forming.
Swap the white pepper
How well each one fits the dish's main ingredients (barley, beef, onion, turnip, celery, flour, pepper):
- Parsleyfits better
- Thymefits better
- Turmericfits better
- White pepperthe original
Fit is the average pairing score against barley, beef, onion, turnip, celery, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
