Why it works: Leek and carrot match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 1,310 recipes. Both carry coumarin, which smells sweet, hay. 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 the meat
Remove the bones from the beef and veal shanks.
Tie the meat securely.
Place the meat in a large pot.
Simmer the stock
Add 3 liters of water and 9 grams of coarse sea salt.
Bring to a boil.
Skim off any foam.
Add leeks, carrots, and onions.
Cook for 5 hours.
Strain through a cloth into a bowl.
Reserve the stock for use.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef shank
- Gives the stock its body and meaty flavour as it cooks slowly.
- Veal shank
- Adds gelatin from the bones and bones, giving the stock a fuller mouthfeel.
- Leeks
- Contribute sweet, mild aromatic flavour to the stock during the long simmer.
- Carrots
- Add gentle sweetness and aromatic depth to the stock.
- Onions
- Add savoury depth and aroma to the stock as they simmer.
The step that matters
Skim off any foam. Foam contains coagulated proteins and impurities that can cloud the stock and taint its flavour. Removing it early keeps the stock clear and clean-tasting through the long simmer.
