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.

Sugar and lemon 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

Egg yolks
Thicken the milk into a smooth custard and add richness.
Milk
Forms the liquid base of the custard that sets when heated and cooled.
Egg whites
Whipped and spread on top, they form a light, airy floating layer.

The step that matters

Stir constantly over heat until it boils. Egg yolks can curdle or scramble if overheated or left still, so constant stirring keeps the custard smooth as it thickens.

Swap the coconut

The recipe marks coconut as optional. How well each one fits the dish's main ingredients (egg, milk, sugar, lemon):

  1. Vanillafits better
  2. Orangefits better
  3. Figfits better
  4. Coconutthe original

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