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

What each ingredient does

Gelatine
Sets the liquid into a firm, sliceable jelly as it cools.
Lemon juice
Adds acidity that brightens the sweetness of the fruit.
Oranges
Contribute juice and sweetness, adding moisture and flavour to the jelly.
Bananas
Add soft texture and natural sweetness to the set jelly.
Malaga grapes
Add juicy bursts of sweetness and moisture throughout the jelly.
English walnuts
Add crunch and a nutty aroma that contrasts with the soft jelly.

The step that matters

Dissolve the gelatine in cold water before adding boiling water. Gelatine must first hydrate in cold liquid so its proteins disperse evenly; adding it straight to hot liquid can leave lumps and weaken the set once chilled.
