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

What each ingredient does

Powdered sugar
Dissolves into the syrup and provides the sweetness and body of the frosting.
Egg white
Beaten stiff, it adds airy volume and a light, fluffy texture to the frosting.
Chopped raisins
Add chewy texture and natural sweetness throughout the frosting.
Chopped english walnuts
Add crunch and a nutty flavor that contrasts with the soft frosting.

The step that matters

Simmer gently until the mixture forms a string. Sugar syrup that is cooked too briefly stays runny and will not set, while overcooking makes it hard and grainy. Gentle heat lets the syrup reach the right concentration evenly.

Swap the raisin

How well each one fits the dish's main ingredients (sugar, egg, walnut, coconut, vanilla):

  1. Figfits better
  2. Blueberryfits better
  3. Cherryfits better
  4. Raisinthe original

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