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.
Place the beef and barley in a saucepan with the 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 off 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 as it simmers, thickening the broth and giving it body.
- Leg of beef
- Long simmering breaks down its connective tissue, flavouring the broth and making the meat tender.
- Ready-browned flour
- Thickens the sauce so it coats the meat.
- Onion
- Adds savoury sweetness and aroma to the broth as it cooks.
The step that matters
Simmering the broth gently. A hard boil makes the meat tough and cloudy, and the broth murky. Keeping it at a slow simmer lets the beef become tender while the broth stays clear and the barley cooks evenly.
Swap the white pepper
How well each one fits the dish's main ingredients (barley, beef, onion, turnip, celery, sauce, flour):
- Capersfits better
- Parsleyfits better
- Thymefits better
- White pepperthe original
Fit is the average pairing score against barley, beef, onion, turnip, celery, sauce, flour. Candidates are from the same food group and used in at least 100 recipes.
