Why it works: Pepper and carrot match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 14,555 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the soup
In a pot, combine beef, onion, water, salt, and pepper.
Add carrot and bay leaf; bring to a boil.
Simmer for 1-2 hours until beef is tender.
Finish and serve
Remove beef, shred it, and return to the pot.
Stir in vinegar and Worcestershire sauce before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main protein and rich meaty flavour as it simmers.
- Onion
- Adds savoury, sweet depth to the broth as it cooks.
- Vinegar
- Adds acidity that brightens the finished soup.
- Worcestershire sauce
- Adds savoury, tangy depth to the finished soup.
The step that matters
Simmer until the beef is tender. Beef is tough raw and needs long, gentle simmering so its connective tissue breaks down. Boiling hard can toughen the meat and cloud the broth, so keep it at a slow simmer.
