Why it works: Carrot and turnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Scotch Barley Broth
Ingredients
Directions
In a large pot, bring 2 gallons of cold water to a boil.
Add 6 ounces of barley and skim the surface.
Add the fowl and 1 pound of beef (or 3 pounds of beef without the fowl).
Stir in 3 pounds of carrots, 3 pounds of turnips, and 3 finely chopped onions.
If using greens, add them and 1 ounce more barley.
Keep the pot boiling for 5 hours, skimming as needed.
Remove the fowl when cooked and serve it with the broth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barley
- Thickens the broth as its starch releases during long simmering, giving body.
- Carrots
- Add sweetness and color to the broth as they soften over the long cook.
- Turnips
- Contribute mild sweetness and soften into the broth during the long boil.
- Onions
- Build savory depth and aroma as they cook down into the broth.
- Beef
- Releases gelatin and flavor into the water, enriching the broth over long simmering.
The step that matters
Keep the pot boiling for 5 hours, skimming as needed. A steady boil over a long time breaks down collagen and draws out flavor, but skimming removes foam and impurities that would otherwise cloud the broth and taste off.
Swap the onion
How well each one fits the dish's main ingredients (barley, beef, carrot, turnip):
- Leekfits better
- Parsnipfits better
- Beetrootfits better
- Onionthe original
Fit is the average pairing score against barley, beef, carrot, turnip. Candidates are from the same food group and used in at least 100 recipes.
