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 meat
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.
Add enough water to match the weight of the meat in quarts.
Simmer the soup
Set over moderate heat until boiling, then skim off any scum.
Cover and simmer gently for 2 hours.
Skim again and add the carrot, turnip, leek, parsley, potatoes, and barley.
Cover and simmer for 1 hour.
Mix the flour with water to make a thickening, stir it in, and cover for 15 minutes.
Serve
Serve the soup with the meat, garnished with parsley, and offer mustard and ketchup on the side.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef
- Slow simmering breaks down connective tissue, making the meat tender and enriching the broth.
- Pearl barley
- Its starch thickens the broth and adds body as it cooks.
- Potatoes
- They soften during simmering and add starch that gives the soup substance.
- Wheat flour
- Mixed with water and stirred in, it thickens the broth at the end.
The step that matters
Skim off the scum after boiling. Foam rising from the meat contains impurities and proteins that can cloud the broth and give it an off flavor if left in. Removing it keeps the soup clear and clean-tasting.
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.
