Shared aroma: 2-nonenal (fatty, green).
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
- Sugar
- Sweetens the ice and lowers its freezing point, keeping it softer and less rock-hard.
- Lemon juice
- Adds tartness and bright acidity that balances the sweetness of the syrup.
- Lemon rind
- Its oils release aroma into the hot syrup, giving a fresh lemon fragrance.
- Mint (in the method)
- Adds a cool, aromatic herbal note that stands out against the lemon.
The step that matters
Add the mint when half-frozen. Mint added at the half-frozen stage stays distributed through the ice. Adding it to a liquid mix can leave it floating, while adding it fully frozen makes it hard to fold in evenly.
