Maple Walnuts

Ingredients

Directions

Make the frosting

  1. Beat the egg white until stiff.

  2. Stir in enough powdered sugar to achieve a hard frosting consistency.

Make the syrup and coat the walnuts

  1. In a saucepan, boil the maple sugar and water for 2–3 minutes to create a syrup.

  2. Dip the walnut halves in the syrup.

Assemble and set

  1. Press some of the hard frosting between two walnut halves and let it harden.

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

What each ingredient does

Egg white
Whipped into a stiff foam that gives the frosting its light structure.
Powdered sugar
Stiffens the whipped egg white into a frosting that sets firm as it hardens.
Maple sugar
Dissolves and boils into a syrup that adds maple sweetness and flavor.
Walnut halves
Provide the crunchy texture and nutty flavor that the frosting and syrup coat and hold.

The step that matters

Boiling the maple syrup. As water evaporates, the sugar concentration rises, so the syrup thickens. Boiling for the stated 2–3 minutes helps it coat the walnuts and set rather than stay runny.

Swap the walnut

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

  1. Pecansfits better
  2. Almondfits better
  3. Chestnutfits about as well
  4. Walnutthe original

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