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
Make the base
In a pot, combine the pineapple, water, lemon juice, and gelatin. Stir until the gelatin is dissolved.
Heat the mixture on the stove until it just comes to a scald, then strain it while warm.
Freeze
Allow the mixture to cool, then freeze it until it reaches a mushy consistency.
Stir in the beaten egg white, then continue to freeze until solid.

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
- Helps set the frozen mixture with a smoother, less icy texture.
- Egg white
- Adds airy lightness and body to the frozen mixture when beaten and folded in.
- Lemon juice
- Adds acidity that brightens the sweetness of the pineapple.
- Pineapple
- Provides the main fruit flavor and sweetness.
The step that matters
Stir in the beaten egg white at the mushy stage. Folding the egg white into a partly frozen base keeps it airy and distributed. If the base is fully solid or still liquid, the white will not blend evenly and the texture suffers.
Swap the pineapple
How well each one fits the dish's main ingredients (lemon, gelatin, sugar, egg):
- Vanillafits better
- Orangefits better
- Raspberryfits about as well
- Pineapplethe original
Fit is the average pairing score against lemon, gelatin, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
