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 ↓

Ingredients
Directions
Prepare the beef
Choose a tender piece of round beef and bind it with tape or cloth to keep its shape.
Heat the drippings in a saucepan, add the beef, and brown it evenly.
Simmer the broth
Add 4 quarts of boiling water and 1 teaspoon of salt, then simmer gently.
Remove the scum as it rises, adding ⅓ cup of cold water every 15 minutes until clear.
Simmer for 3 hours.
Prepare the vegetables
Meanwhile, scrape and quarter the carrots, peel the onions and turnips, and stick 10 whole cloves in one onion.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rump beef
- Long, gentle simmering breaks down connective tissue, leaving the meat tender and easy to slice.
- Drippings
- Browning the beef in fat builds roasted, savory flavor that carries into the broth.
- Carrots
- Release natural sugars as they cook, adding gentle sweetness and color to the broth.
- Small white turnips
- Soften during simmering and add mild sweetness to the broth.
- Onion
- Cooking releases savory aromatic compounds that deepen the flavor of the broth.
The step that matters
Removing the scum as it rises. Scum is coagulated protein and impurities. Skimming it as it forms, and adding cold water so it rises and sets, keeps the broth clear and clean-tasting.
