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 ↓
Scotch Barley Broth
Ingredients
Directions
Prepare and start the broth
Wash the barley in cold water.
Place the barley in a soup pot with the beef, cut into four pieces.

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 adds a chewy texture as its starch releases during simmering.
- Beef shin or leg
- Releases flavor and gelatin into the broth during long, gentle simmering.
- Onions
- Add savory sweetness and aromatic depth to the broth.
- Celery
- Contributes aromatic, savory flavor to the broth.
- Turnip
- Adds mild sweetness and body to the vegetables and broth.
The step that matters
Simmer gently after bringing to a boil. Once the broth boils, reducing heat to a gentle simmer keeps the meat tender and the broth clear. A hard, rolling boil toughens meat fibers and emulsifies fat into the liquid, making the broth cloudy and greasy.
Swap the onion
How well each one fits the dish's main ingredients (barley, beef, celery, turnip):
