Why it works: Pineapple and lemon are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 1,964 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Pineapple Ice
Ingredients
Directions
Prepare the base
In a large pot, combine sugar and water, and bring to a boil until the sugar dissolves.
Add the grated pineapple, lemon juice, and grated lemon rind to the mixture.
Add the eggs and freeze
In a separate bowl, beat the egg whites until stiff peaks form.
Fold the beaten egg whites into the pineapple mixture last.
Mix in the flour and starch until well combined.
Pour the mixture into a suitable container and freeze until solid.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Eggs
- Whipped whites trap air, giving the frozen ice a lighter, more airy texture.
- Sugar
- Sweetens the mixture and lowers the freezing point, keeping the ice softer.
- Lemons
- Juice adds acidity that brightens the pineapple flavor; rind adds aroma.
- Pineapple
- Provides the main fruit flavor and moisture for the ice.
The step that matters
Fold the beaten egg whites into the pineapple mixture last. Stiff whites hold air only if they are folded gently and added at the end. Stirring them vigorously or adding them too early deflates the foam, leaving a denser, less airy ice.
Swap the pineapple
How well each one fits the dish's main ingredients (sugar, egg, lemon, flour):
- Raisinfits better
- Vanillafits better
- Orangefits better
- Pineapplethe original
Fit is the average pairing score against sugar, egg, lemon, flour. Candidates are from the same food group and used in at least 100 recipes.
