Prepare
Dissolve the isinglass in ½ cup water with a little sugar and lemon peel, cleared with the white of an egg.
Boil the ½ pound sugar in a small teacup of water until it reaches candy height.
Boil the lemon peel in a little water.
Make the jelly

Pour the mixture into a mold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Isinglass
- Sets the liquid into a firm jelly as it cools.
- Sugar
- Sweetens the punch and forms the syrup that is blended into the liquid.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sweetness.
- Rum
- Adds aroma and flavour, with alcohol that contributes to the punch's character.
- Brandy
- Adds aroma and warmth to the flavour of the punch.
The step that matters
Dissolve the isinglass fully before adding it. Isinglass must be completely dissolved in warm liquid so it sets evenly; undissolved pieces leave a cloudy or lumpy jelly with weak spots.
Swap the lemon
