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 ↓

Ingredients
Directions
Make the base
Squeeze the juice from the lemons and orange, and steep it with the grated rinds for 2 hours.
Strain the mixture through a towel.
Add 1 pint of water and 2 cups of sugar, stirring until dissolved.
Freeze
Pour the mixture into a freezer and freeze, letting it stand for 2 to 3 hours.

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 defines the flavour of the ice.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the ice softer.
- Lemon rind
- Contributes aromatic oils that add fragrance and bitter depth.
- Orange juice
- Adds sweetness and a mellower citrus note alongside the lemon.
The step that matters
Dissolving the sugar fully. Sugar must dissolve completely before freezing, because undissolved crystals create a gritty texture and sugar also lowers the freezing point so the ice stays scoopable.
