Why it works: Gelatin and sugar 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 ↓

Ingredients
Directions
Prepare the mixture
Soak the gelatin in cold water for 1 hour.
Pour 1 pint of hot water over the soaked gelatin.
Mix the gelatin water with the shredded pineapple, lemon juice, and sugar.
If the mixture is less than 3 pints, add cold water to fill it up.
Freeze and finish
Place the mixture in the freezer.
When partially frozen, fold in the stiffly beaten egg white.

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 into a light, firm body that holds its shape when frozen.
- Egg white
- Whipped and folded in, it adds air and a lighter, fluffier texture.
- Sugar
- Adds sweetness and softens the frozen texture so it is less icy and hard.
- Lemon juice
- Adds acidity that balances the sweetness and brightens the pineapple flavour.
The step that matters
Folding in the egg white when partially frozen. If the mixture is fully frozen, the stiffly beaten egg white cannot blend in evenly and the ice loses its airy texture. If it is still liquid, the whites deflate and the mixture stays dense.
Swap the pineapple
How well each one fits the dish's main ingredients (gelatin, lemon, sugar, egg):
- Vanillafits better
- Orangefits better
- Raspberryfits about as well
- Pineapplethe original
Fit is the average pairing score against gelatin, lemon, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
