    Shared aroma: beta-damascenone (apple, rose).

Sugar and lemon 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 structure as it cools and hardens.
Sugar
Adds sweetness and balances the sharpness of the citrus juices.
Lemon juice
Adds acidity and bright citrus flavour.
Orange juice
Adds fruity sweetness and aroma to the base.

The step that matters

Cool until partly congealed before beating. Gelatine begins to set as the mixture cools. If it is still too runny, it will not hold air when beaten. If it is too set, it will not whip smoothly. Partly set gelatine traps air in a stiff, stable froth.
