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

What each ingredient does

Tapioca
Swells in water and thickens the mixture as it cooks, giving the cream its body.
Egg whites
Add airy lightness and some structure to the cooked cream when stirred in.
Sugar
Sweetens the cream and balances the sharpness of the lemon and pineapple.
Lemon juice
Adds acidity that brightens the flavour and cuts the sweetness.

The step that matters

Stirring in the egg whites just before removing from heat. Egg whites set when heated, so adding them too early can cook and toughen them. Adding them just before removing from heat keeps them light while they partly set in the hot mixture.

Swap the pineapple

How well each one fits the dish's main ingredients (sugar, lemon, egg, cream):

  1. Vanillafits better
  2. Raspberryfits better
  3. Orangefits better
  4. Pineapplethe original

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