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.
- Granulated sugar
- Adds sweetness and helps give the jelly its body.
- Oranges
- Provide the main juice and flavour of the jelly.
- Lemons
- Add acidity that brightens the orange flavour.
The step that matters
Dissolving the gelatine in boiling water. Gelatine must fully dissolve for an even set; undissolved granules leave gritty or weak patches. Stirring frequently in hot water helps it dissolve completely before the juice is added.
