Why it works: Sugar and gelatin are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,778 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Pineapple Ice
Ingredients
Directions
Prepare
Soak the gelatin in a little water for 2 hours.
Boil the water and sugar for 5 minutes, then set aside to cool.
Chop the pineapple finely or strain out the juice, as preferred.
Make and freeze
Mix the lemon juice, syrup, and gelatin, then strain the mixture.
Add the pineapple and freeze the mixture.
When nearly frozen, fold in the beaten whites of the eggs.

Lemon and sugar 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
- Gelatin
- Sets the liquid so the ice holds a smooth, firm texture when frozen.
- Egg whites
- Whipped whites add air and lightness to the frozen mixture.
- Sugar
- Sweetens the syrup and softens the texture of the frozen ice.
- Lemons
- Add acidity that brightens the sweetness of the syrup and pineapple.
The step that matters
Folding in the beaten egg whites. Fold gently when the mixture is nearly frozen so the whites keep their air. Stirring hard or letting it freeze fully first knocks air out and makes the ice dense.
Swap the pineapple
How well each one fits the dish's main ingredients (lemon, sugar, gelatin, egg):
- Vanillafits better
- Orangefits better
- Raspberryfits about as well
- Pineapplethe original
Fit is the average pairing score against lemon, sugar, gelatin, egg. Candidates are from the same food group and used in at least 100 recipes.
