Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Port wine
- Forms the liquid base and gives the jelly its flavour and colour.
- Isinglass
- A gelatin-like protein that dissolves on heating and sets the liquid into a firm jelly as it cools.
- Gum arabic
- Helps stabilise the liquid and adds body so the jelly holds together more evenly.
- Sifted sugar
- Adds sweetness and balances the strong, tannic flavour of the port.
The step that matters
Simmering until fully dissolved. Isinglass must dissolve completely for the jelly to set evenly. Gentle heat in the water bath dissolves the protein without breaking it down, while a rolling boil can weaken its setting power and make the jelly cloudy or soft.
