Why it works: Turnip and capers match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 145 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
A Cheap Soup
Ingredients
Directions
Prepare
Wash the barley in cold water.
In a soup pot, combine the barley and beef with enough cold water to cover.
Bring to a boil, skim off any foam, and add the onions.
Simmer the soup
Reduce heat and simmer gently for 2 hours.
Skim off fat, then add celery and turnip.
Season with salt and boil for another 1.5 hours.
Make the sauce and serve
Remove the meat and keep warm.
Skim the broth and pour 1 quart into a basin.
In a separate pan, mix flour with the broth gradually, stirring well.
Heat the mixture until it boils, then let it boil briefly.
Serve the meat on a dish and strain the sauce over it.
Add capers, gherkins, or walnuts if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barley
- Thickens the soup as it cooks and gives it a hearty, chewy texture.
- Beef shin or leg
- Long simmering breaks down connective tissue, enriching the broth with body and savory flavor.
- Flour
- Stirred into broth and boiled, it thickens the liquid into a smooth sauce.
- Onions
- Release sweetness and aroma into the broth as they simmer.
The step that matters
Stirring the flour into the broth. Adding flour gradually while stirring keeps it from forming lumps. Boiling then cooks out the raw starch taste and fully thickens the sauce.
Swap the capers
The recipe marks capers as optional. How well each one fits the dish's main ingredients (barley, beef, onion, celery, turnip, flour):
- Capersthe original
- Thymefits about as well
- Turmericfits about as well
- Parsleyfits about as well
Fit is the average pairing score against barley, beef, onion, celery, turnip, flour. Candidates are from the same food group and used in at least 100 recipes.
