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
Prepare
Measure the water into a strong pan and add the salt.
Wipe and cut the meat into small pieces, removing fat and skin, and add to the water.
Scrape the bone well, remove the marrow, wash to remove fat, and add to the pan.
Make the stock
Bring the stock slowly to a boil, about 45 minutes.
Remove any gray scum that forms on the surface.
Add the prepared vegetables cut into large pieces.
Simmer the stock for 3 to 4 hours.
Strain through a fine sieve.
When cold, skim off the fat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef shin or shoulder
- Provides meat flavour and gelatin-rich connective tissue that gives the stock body.
- Bones (in the method)
- Release collagen and marrow during long simmering, adding body and richness to the stock.
- Onion
- Adds savoury sweetness and aromatic depth as it cooks slowly in the liquid.
The step that matters
Removing the gray scum. Scum is coagulated protein and impurities that rise as the liquid heats. Skimming it early keeps the stock clear and clean-tasting rather than cloudy or bitter.
Swap the onion
How well each one fits the dish's main ingredients (beef, carrot, celery):
- Parsnipfits better
- Turnipfits better
- Tomatofits better
- Onionthe original
Fit is the average pairing score against beef, carrot, celery. Candidates are from the same food group and used in at least 100 recipes.
