Why it works: Carrot and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,173 recipes. Both carry myristicin, which smells spice, warm. 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 pot
Rub a large stew‑pan or stock‑pot with a coarse cloth.
Grease the bottom and sides with marrow or melt a large piece of butter.
Make the broth
Add the beef, veal, mutton, and any fresh meat trimmings.
Add the carrot, celery, onions, leeks, and turnip.
Heat over a brisk fire until it catches but does not burn.
Pour in 5 quarts of soft water and scum carefully.
Add 1 pint of cold water to raise more scum.
Simmer slowly for 4 hours.
Let it settle by the hearth, skim off the fat, and strain.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef
- Gives the broth its meaty body and rich flavour as it simmers.
- Veal knuckle
- Adds gelatine from bones and connective tissue, giving the broth body.
- Mutton shanks
- Contribute bone and connective tissue for extra depth and body in the stock.
- Onions
- Add sweetness and savoury aroma as they cook into the broth.
- Celery
- Adds aromatic flavour to the broth as it simmers.
The step that matters
Scumming and simmering slowly. Letting the liquid boil hard emulsifies fat and proteins into the broth, making it cloudy. Keeping it at a gentle simmer and skimming scum lets impurities rise so the broth stays clear.
Swap the celery
How well each one fits the dish's main ingredients (beef, veal, mutton, meat, carrot, onion, leek):

Fit is the average pairing score against beef, veal, mutton, meat, carrot, onion, leek. Candidates are from the same food group and used in at least 100 recipes.
