Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Port wine
Provides the main flavour and the wine's colour, with sweetness balanced by the lemon.
Isinglass or fine gelatine
Sets the liquid into a firm jelly as it cools.
Lemon
Adds acidity that brightens the sweet wine and balances its flavour.
Sugar
Adds sweetness to balance the wine's tartness and astringency.

The step that matters

Stirring in the gelatine until fully dissolved. Gelatine only sets properly when it is completely dissolved into the hot liquid. Undissolved granules leave weak spots and a grainy texture in the finished jelly.
