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

What each ingredient does

Sugar
Dissolves in water to form a syrup that sets the icing's sweet, glossy body.
Eggs
Whites whipped into a stiff foam give the icing its light, airy structure.

The step that matters

Pouring the boiling syrup over the whites while beating. The hot syrup must be poured in a steady stream while beating constantly, so it cooks and stiffens the egg whites evenly. Pouring too fast or stopping early can leave the icing runny or grainy.

Swap the raisin

How well each one fits the dish's main ingredients (sugar, flour, milk, butter, cream, tea, egg):

  1. Vanillafits better
  2. Raisinthe original
  3. Peachfits about as well
  4. Figfits about as well

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