The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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):

  1. Vanillafits better
  2. Orangefits better
  3. Raspberryfits about as well
  4. 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.
