Why it works: Thyme and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. 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.
Prepare
In a large pot, place the beef shank and cover with water.
Add the carrots, onions, leek, bouquet garni, salt, and pepper.
Cook
Bring to a boil, then reduce heat and simmer for 2-3 hours until the meat is tender.
Skim off any foam that rises to the surface during cooking.
Serve
Remove the meat and vegetables, strain the broth, and serve hot.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef shank
- Slow simmering breaks down connective tissue, making the meat tender and enriching the broth with gelatin.
- Carrots
- Release sweetness and body into the broth as they cook.
- Onions
- Add savory sweetness and aroma to the broth.
- Leek
- Adds a mild onion-like aroma and sweetness to the broth.
The step that matters
Skim off the foam. Foam rising during the boil contains coagulated proteins and impurities. Removing it keeps the broth clear and clean-tasting instead of cloudy or scummy.
Swap the onion
How well each one fits the dish's main ingredients (beef, carrot, leek, thyme, parsley, pepper):

Fit is the average pairing score against beef, carrot, leek, thyme, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
