Why it works: Turnip and carrot 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 Broth
Ingredients
Directions
Prepare the barley
Soak the barley overnight in 3 quarts of water.
Simmer the soaked barley for 1 hour.
Make the broth
Heat the oil in a pot, add chopped vegetables, and cook for 2 minutes.
Add the cooked vegetables to the barley and slowly cook until both the vegetables and barley are tender.
Adjust seasoning with more salt and pepper if necessary.
If the broth is too thick, add more water.
For added flavor, stir in 1 tablespoon of peanut butter or Vegex.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Scotch barley
- Provides the main body and chewy texture as it softens and releases starch into the broth.
- Onions
- Add sweetness and savory depth as they soften in the hot oil.
- Carrot
- Adds sweetness and color, and becomes tender during the slow simmer.
- Turnip
- Adds a mild, slightly peppery flavor and firm texture that softens with cooking.
The step that matters
Simmer the barley until tender. Barley needs a long, gentle simmer to soften fully. Adding the vegetables too early or cooking too hard can leave the grains chewy or break up the texture.
Swap the onion
How well each one fits the dish's main ingredients (barley, beans, corn, turnip, carrot, pepper):
