Why it works: Celery and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 18,518 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Veal or White Stock
Ingredients
Directions
Prepare
Wipe the veal and break the bones.
Place the veal in a pot with cold water.
Simmer
Heat slowly and simmer for 4 hours, skimming regularly.
Add celery, onion, bay leaf, and salt, then simmer for 1 hour more.
Cool and finish
Let cool; it should jelly when cold, and the fat can be easily removed.
Melt the stock for use and strain through cheesecloth or clarify with egg if needed.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Knuckle of veal
- Bones and connective tissue release gelatin, which lets the stock set into a jelly when cold.
- Cold water
- Slow extraction from a cold start draws flavour and gelatin out of the bones gradually.
- Celery
- Adds a fresh, aromatic background flavour to the stock.
- Onion
- Adds sweetness and savoury depth as it simmers into the stock.
- Bay leaf
- Contributes a subtle herbal aroma to the stock.
The step that matters
Simmer gently and skim regularly. A rolling boil emulsifies fat and impurities into the liquid, making the stock cloudy and greasy. Gentle simmering and skimming keep it clear, so it sets cleanly when cold.
Swap the celery
How well each one fits the dish's main ingredients (veal, onion):
- Garlicfits better
- Celerythe original
- Capersfits about as well
- Thymefits about as well
Fit is the average pairing score against veal, onion. Candidates are from the same food group and used in at least 100 recipes.
