Ingredients
Directions
Prepare
Soak the gelatine in 1 pint of water.

Lemon and sugar barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
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, wobbly jelly as it cools.
- Sugar
- Adds sweetness and helps balance the tartness of the citrus juice.
- Oranges
- Provide the main juice, flavour and aroma of the jelly.
- Lemons
- Add acidity that brightens the flavour and balances the sweetness.
The step that matters
Stirring the gelatine into the boiling water. Gelatine must be fully dissolved before the mixture sets; undissolved granules leave gritty spots and weak patches in the jelly. Stirring constantly while it is hot helps it disperse evenly.
