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

What each ingredient does

Sugar
Dissolved in water and boiled into syrup, which gives the filling its sweetness and body.
Egg whites
Whipped with the hot syrup to form a light, airy, stable foam that gives the icing its structure.
Water
Dissolves the sugar so it can be boiled into a syrup of the right concentration.

The step that matters

Slowly pour the hot syrup over the beaten egg whites. Pouring the hot syrup in a thin, slow stream while beating lets it cook the egg whites gently and build a smooth, stable foam. Pouring it all at once can deflate the whites or leave cooked lumps.

Swap the coconut

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

  1. Figfits better
  2. Blueberryfits about as well
  3. Peachfits about as well
  4. Coconutthe original

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