Why it works: Celery and tarragon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 456 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Aspic Jelly
Ingredients
Directions
Make the stock
Cover the veal marrowbone and hock with 3 quarts of water.
Cook slowly until the meat slips from the bone and the hock is soft.
When partly cooked, add salt, pepper, onion, bay leaf, and celery.
Strain and set
Remove the meat and strain the liquid, which should be about 2 quarts.
Add tarragon vinegar to taste and refrigerate until the next day.
If the jelly is solid enough to cut, it is ready.
If it is too soft, boil the hock longer.
Mold and serve
While lukewarm, mold the jelly with nuts, meats, tomatoes, or cucumbers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal marrowbone and hock
- Releases gelatin as it simmers, which lets the liquid set into a firm jelly.
- Water
- Extracts gelatin and flavor from the bones and meat during slow cooking.
- Tarragon vinegar
- Adds acidity that brightens the flavor of the jelly.
The step that matters
Judging the set before molding. Gelatin sets as the liquid cools, so the jelly must be checked after chilling. If it is too soft, it will not hold its shape when molded. Boiling the hock longer concentrates the gelatin and improves the set.
Swap the onion
How well each one fits the dish's main ingredients (veal, pepper, celery, tarragon, vinegar):
- Mustardfits better
- Carrotfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against veal, pepper, celery, tarragon, vinegar. Candidates are from the same food group and used in at least 100 recipes.
