Why it works: Turnip and leek match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,046 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Shin of Beef Soup
Ingredients
Directions
Prepare the beef
Have the butcher saw the shin-bone into 2-inch pieces.
Wash the meat in cold water.
Mix salt and pepper, rub it into the meat, and place it in a soup pot.
Simmer the soup
Add water equal to the weight of the meat and bring to a boil.
Skim off any scum, cover, and simmer gently for 2 hours.
Skim again, then add the carrot, turnip, leek, parsley, potatoes, and barley.
Cover and simmer for 1 hour.
Add another tablespoon of salt and a thickening made from flour and water, stirring it in.
Cover and cook for an additional 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef
- Collagen-rich connective tissue breaks down during long simmering, giving the broth body and tender meat.
- Wheat flour
- Mixed with water and stirred in, it thickens the broth as it cooks.
- Pearl barley
- Swells and softens during simmering, adding body and starch to the soup.
- Potatoes
- Soften through simmering and release starch that thickens the broth slightly.
The step that matters
Skim off the scum. Skimming the foam that rises during the first boil removes impurities and proteins, keeping the broth clearer and cleaner in flavor.
Swap the potato
How well each one fits the dish's main ingredients (beef, pepper, carrot, turnip, leek, parsley, barley):
- Parsnipfits better
- Shallotfits better
- Chivefits better
- Potatothe original
Fit is the average pairing score against beef, pepper, carrot, turnip, leek, parsley, barley. Candidates are from the same food group and used in at least 100 recipes.
