Why it works: Orange and lemon 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 ↓
Orange Ice
Ingredients
Directions
Make the syrup
Combine sugar and water in a pot to make a syrup.
Skim the syrup well and let it cool.
Add the flavours
Juice the oranges and add the juice to the cooled syrup.
Boil the rinds of the oranges in water, then strain the water into the syrup.
Add the juice and rind of the lemon in the same way.
Freeze
Freeze the mixture until solid.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 so it stays softer and scoopable.
- Oranges
- Supply the main juice and aromatic oil from the peel, giving flavour and sweetness.
- Lemon
- Adds acidity that brightens the orange flavour.
The step that matters
Skim the syrup well and let it cool. Skimming removes foam and impurities that would cloud the ice and affect its texture. Cooling the syrup before adding juice prevents heat from damaging the fresh juice's flavour and keeps the mixture from melting or separating prematurely.
