Why it works: Lemon and orange match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓

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
- Lemons
- Provide the main acidity and citrus aroma, with the rind adding fragrant oils.
- Sugar
- Sweetens the ice and, dissolved in the liquid, lowers its freezing point for a softer texture.
- Orange
- Adds extra juice and a milder, sweeter citrus flavour alongside the lemon.
The step that matters
Stirring during freezing. Stirring breaks up ice crystals as they form, keeping the ice fine and smooth rather than hard and icy. Skipping the repeated stirring lets large crystals develop.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
