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.
Oranges
Provide the main fruit flavour and pieces suspended in the jelly.
Sugar
Sweetens the jelly and balances the tartness of the citrus.
Lemons
Add acidity that brightens the flavour of the orange and sugar.

The step that matters

Soak the gelatine until swollen. Gelatine must hydrate in cold water before it meets hot liquid. Adding it dry or to hot liquid directly can cause clumping and uneven setting, so the jelly may not set smoothly.
