Why it works: Pineapple and sugar are a kitchen classic. They rank in the top 19% of all ingredient pairs, and cooks put them together in 4,841 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Pine-apple Ice
Ingredients
Directions
Prepare the pineapple
Remove the pineapple from the juice and chop it finely, discarding any black specks.
Make the syrup
In a pot, boil together the sugar and water to make a thick syrup for a few minutes.
While the syrup is hot, pour it over the chopped pineapple and add the juice from the cans.
Finish and freeze
Once cooled, mix in the citric acid, beaten egg whites, and additional water.
Freeze the mixture until firm.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pineapple
- Provides the main fruit flavour and acidity, and its juice adds moisture to the ice.
- Sugar
- Sweetens the ice and lowers its freezing point so it stays softer.
- Egg whites
- Whipped proteins add airy structure and lightness to the frozen mixture.
- Citric acid
- Adds tartness that brightens the pineapple flavour and balances the sugar.
The step that matters
Freezing the mixture until firm. Sugar and acid lower the freezing point and ice crystals form slowly, so the mixture needs time to set fully and stay smooth rather than icy in texture.
Swap the pineapple
How well each one fits the dish's main ingredients (sugar, egg):

Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
