Cold Icing

Ingredients

Directions

Make the icing

  1. Beat the egg until it froths.

  2. Gradually add 6 ounces of powdered sugar while continuing to beat.

  3. Once thick, add sweet cream, using about 2 tablespoons for each egg.

  4. Flavor with orange flavoring.

  5. The icing should be thicker than cream.

Spread

  1. When spreading, dip your knife in water.

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

What each ingredient does

Egg
Its proteins whip into a foam that gives the icing its light, airy body.
Powdered sugar
Dissolves into the foam and thickens it, providing sweetness and body.
Sweet cream
Adds moisture and softens the mixture to a spreadable consistency.

The step that matters

Adding the powdered sugar gradually. Adding sugar all at once can collapse the foamed egg and leave the icing lumpy or runny. Adding it slowly while beating lets the foam hold and thicken evenly.

Swap the orange

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

  1. Vanillafits better
  2. Raisinfits better
  3. Strawberryfits better
  4. Orangethe original

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