Ingredients
Directions
Prepare the stock
Truss the legs of the fowls inward.
Place them in a small stewpan with veal fragments.
Add the boned calves' feet or knuckles of veal, broth, bay leaf, thyme, basil, parsley, and chives.
Simmer on low heat for 4 hours, skimming regularly.
Strain the mixture through a cloth.
Flavour and clarify
Reduce the tarragon vinegar to half.
Mix the reduced vinegar with white pepper, cloves, and mushroom trimmings.
Add the mixture to the jelly.
Beat the egg whites with white wine and veal gravy.
Mix the beaten mixture into the jelly.
Heat the jelly on strong fire, stirring continuously until it boils.
Simmer for 30-40 minutes, placing a lid with heat on top to clarify the jelly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fowls
- Contribute body and savoury flavour to the stock that sets into the jelly.
- Calves' feet or veal knuckles
- Provide natural gelatin so the stock sets firmly when cooled.
- Egg whites
- Bind and trap solids during boiling, clarifying the jelly to a clear result.
- Tarragon vinegar
- Adds acidity that brightens the jelly's flavour.
- Veal gravy
- Adds concentrated meaty flavour and colour to the clarifying mixture.
The step that matters
Heating the jelly with the egg white mixture. Stirring until it boils and then simmering gently lets the egg whites coagulate and collect impurities. Boiling too vigorously or stirring after the lid is placed can break up the raft, leaving the jelly cloudy.
