Why it works: Chervil and tarragon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 824 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Aspic Jelly
Ingredients
Directions
Make the infused consommé
Boil the herbs in white vinegar until well scented.
Pour the scented vinegar into a stew-pan with the reduced chicken consommé and season well.
Beat the egg whites in an earthen pan with an osier rod.
Add the aspic mixture to the egg whites and heat in a stew-pan, stirring until it becomes white and near boiling.
Cover and place on the corner of the stove with a little heat on top until clear.
Strain through a bag or sieve for use.
Make the firmer jelly
For a firmer jelly, place the veal knuckle, ham, calf feet, and trimmings in a stock-pot with onions, carrots, and herbs, moisten with broth, and boil gently for 4 hours.
Skim off the fat and drain through a silken sieve into a stew-pan.
Add tarragon vinegar, egg whites, salt, and pepper to clarify, stirring until very white.
Set aside with a little heat until clear, then drain through a cloth or jelly-bag.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Collect impurities as they heat, clarifying the liquid so it becomes clear.
- Reduced chicken consommé
- Provides the concentrated savoury liquid that sets into the jelly.
- Calf feet
- Release gelatine during long gentle boiling, helping the jelly set firmer.
- Veal knuckle
- Adds gelatine and body to the stock, helping the jelly set firmer.
- White vinegar
- Extracts the aromatic flavour of the herbs and adds gentle acidity.
The step that matters
Clarifying with egg whites. Heat must be kept gentle once the egg whites begin to set. Boiling hard breaks up the coagulated whites and cloudies the liquid, so it should stay just under a simmer until clear.
