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

Milk
Forms the body of the custard that the meringue rests on.
Eggs
Egg whites whip into a foam that holds its shape and gives the topping its light structure.
Lemon flavoring
Adds a bright aroma that flavors the custard.
Loaf sugar
Adds sweetness to the topping.
Coconut
Adds texture and a toasty-sweet flavor to the top.

The step that matters

Beat the egg whites to stiff peaks. Egg whites must be beaten enough to trap air and hold stiff peaks so the topping stays light. Underbeaten whites collapse and slide off the custard, while overbeaten whites turn dry and grainy.

Swap the coconut

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

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

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