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

What each ingredient does

Eggs
Thicken the custard as they cook and help give it structure.
Gelatine
Sets the liquid custard into a firm, sliceable jelly when chilled.
Milk
Forms the liquid base of the custard and adds richness and body.
Sugar
Sweetens the custard and balances the sherry and lemon.
Sherry
Adds aroma and a warm, fortified wine flavour to the jelly.
Lemon juice
Adds acidity that brightens the sweet custard and sherry.

The step that matters

Stir the gelatine into the custard. Gelatine must be fully dissolved and stirred in evenly while the custard is still warm; if it is added to a cold or lumpy mixture it can set in clumps, and if the custard is too hot it may not set properly. Constant stirring spreads it evenly so the jelly sets smooth and uniform.
