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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Gelatine
Sets the mixture so the frozen ice holds a smooth, firm body.
Sugar
Adds sweetness and lowers the freezing point, keeping the ice soft enough to eat.
Lemon juice
Adds acidity that brightens the flavour and balances the sweetness.
Sweetened milk
Adds fat and milk solids that give a creamier, less icy texture.

The step that matters

Add the sweetened milk at the right moment. Adding milk once the mixture just begins to freeze around the sides lets it blend in evenly. Adding it too early can cause curdling from the acid, and too late leaves streaks and uneven texture.

Swap the lemon

How well each one fits the dish's main ingredients (sugar, pineapple, milk):

  1. Vanillafits better
  2. Figfits better
  3. Strawberryfits better
  4. Lemonthe original

Fit is the average pairing score against sugar, pineapple, milk. Candidates are from the same food group and used in at least 100 recipes.
