What each ingredient does
- Calves' feet
- Provide gelatin that sets the broth into a firm jelly as it cools.
- Sugar
- Adds sweetness and balances the savoury broth and the wine's tartness.
- Port wine
- Adds flavour, aroma and acidity to the jelly.
- Eggs
- Whites and shells collect cloudy particles during boiling so the jelly can be clarified.
The step that matters
Add the egg whites and shells, then boil for 5 minutes. The egg whites coagulate as they heat and trap suspended impurities, forming a raft. Boiling only briefly lets the raft form without breaking up, so straining afterward leaves a clear jelly.
