Maple Walnuts

Ingredients

Directions

  1. Beat the egg white to a stiff froth.

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

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

  4. Dip the walnut meats in the syrup.

  5. Press some of the frosting between the two halves of the walnut 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 to a stiff froth, it forms the airy frosting that binds the walnut halves.
Powdered sugar
Stiffens the whipped egg white into a frosting that holds its shape and sets firm.
Maple sugar
Boiled with water into a syrup that gives the walnuts their maple sweetness and flavor.
Walnut meats
Form the crunchy base that is dipped in syrup and filled with frosting.

The step that matters

Boiling the maple syrup. Boiling for only the stated 2-3 minutes sets the syrup's concentration; boiling too long can make it crystallize or harden too much, while too short leaves it thin and sticky.

Swap the walnut

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

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

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