Why it works: Apple and lemon are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 7,551 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Apple-Water Ice
Ingredients
Directions
Prepare the apples
Pare and core the apples, then cut them into pieces.
Place the apple pieces in a preserving pan with enough water to float them.
Boil until reduced to a marmalade, then strain the mixture.
Make and freeze the ice
Combine 1 pint of apple water with ½ cup of syrup, lemon juice, and a little water.
When cold, freeze the mixture.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the main fruit flavour and, once cooked to a pulp, the liquid base of the ice.
- Syrup
- Adds sweetness and lowers the freezing point, keeping the ice softer and smoother.
- Lemon juice
- Adds acidity that brightens the apple flavour and balances the sweetness.
The step that matters
Boil until reduced to a marmalade. Boiling softens the apples and breaks down their cell walls, releasing pectin and flavour. Stopping too early leaves the pulp thin and watery, while boiling too long concentrates it and can make the ice taste cooked.
Swap the apple
How well each one fits the dish's main ingredients (syrup, lemon):
- Orangefits better
- Limefits better
- Raspberryfits better
- Applethe original
Fit is the average pairing score against syrup, lemon. Candidates are from the same food group and used in at least 100 recipes.
