Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatin
- Sets the liquid into a firm, sliceable jelly as it cools.
- White sugar
- Adds sweetness and helps give the jelly its body.
- Lemon juice
- Adds acidity that balances the sweetness and brightens the flavour.
- Fresh pineapple
- Provides the main fruit flavour for the jelly.
The step that matters
Stir the gelatin until fully dissolved. Undissolved gelatin granules will not hydrate evenly, leaving grainy specks and weak spots in the set jelly. Stirring until clear ensures it is distributed through the hot liquid before it cools.
