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.

Swap the white pepper
