Why it works: Sugar and lemon are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Lemon-Water Ice
Ingredients
Directions
Make the mixture
In a vessel, combine powdered sugar and cold water.
Grate in the lemon rind and squeeze in the lemon juice.
Beat the mixture well for five minutes with a spatula.
Use a syrup-weigher to check the mixture; it should be at twenty-one degrees.
If not, add more powdered sugar until correct.
Freeze
Remove the weigher, mix a little more, and strain through a sieve into a freezer.
Cover and freeze as you would for vanilla cream ice.

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.

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
- Powdered sugar
- Dissolves into the water to sweeten the ice and set its sugar level for freezing.
- Lemon juice
- Adds acidity and bright lemon flavour that balances the sweetness.
- Lemon rind
- Contributes aromatic lemon oils that add fragrance to the ice.
The step that matters
Check the syrup-weigher reading. Sugar sets how easily the mixture freezes and how soft the ice stays. If the reading is off, the ice can freeze too hard or too icy, so adjust the sugar before freezing.
