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

What each ingredient does

Pearl tapioca
Starch that thickens as it cooks and turns the mixture clear and creamy.
Sugar
Adds sweetness and balances the tartness of the lemon and pineapple.
Lemon juice
Adds acidity that brightens the flavour and cuts the sweetness.
Pineapple
Provides fruit flavour and moisture to the pudding.
Egg whites
Whipped and folded in to lighten the texture of the pudding.

The step that matters

Fold in the beaten egg whites. Egg whites hold air only when whipped and kept unfolded as little as possible; once cooled, gentle folding keeps the pudding light instead of deflating it.

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.
