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 ↓

Ingredients
Directions
Make the syrup
Make a syrup by boiling 1 pint of water with 1½ pounds of sugar until clear.
Pour the hot syrup over the can of pineapple.
Freeze
Add enough cold water to make 1 gallon of mixture and stir in the juice of 2 lemons.
Pour the mixture into a freezer.
When it starts to freeze, stir in the beaten egg whites.

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
- Granulated sugar
- Dissolves into the syrup to sweeten the ice and lower its freezing point for a softer texture.
- Pineapple
- Provides the main fruit flavour and body in the mixture.
- Lemon juice
- Adds acidity that brightens the sweetness of the syrup and pineapple.
- Egg whites
- Whipped into the partly frozen mixture to add air and a lighter, smoother texture.
The step that matters
Stir in the beaten egg whites when the mixture starts to freeze. If added to a fully frozen or still liquid mixture, the whites will not blend evenly. Partial freezing keeps the mixture slushy enough to fold the whites in, which gives a lighter texture.
Swap the pineapple
How well each one fits the dish's main ingredients (sugar, lemon, egg):
- Orangefits better
- Vanillafits better
- Limefits better
- Pineapplethe original
Fit is the average pairing score against sugar, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
