Shared aroma: 2-nonenal (fatty, green).
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
- Lemon juice
- Provides the sharp acidity that balances the sweetness of the sugar.
- Powdered sugar
- Sweetens the drops and, as it dissolves and cooks, sets into a firm, glossy candy.
The step that matters
Stir constantly while boiling. Sugar and lemon juice can scorch on the bottom of the pan if not stirred, giving a bitter, browned flavour. Constant stirring keeps the heat even so the mixture reaches a clean set once cooled.
