Ingredients

Directions

  1. In a bowl, mix the confectioners' sugar, grated orange rind, and enough orange juice to moisten the sugar.

  2. Add the egg yolk and melted butter to the mixture.

  3. Beat all ingredients together until the mixture is just stiff enough to spread.

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

What each ingredient does

Confectioners' sugar
Provides sweetness and the bulk that gives the frosting its body.
Egg yolk
Adds richness and emulsifies with the butter to help hold the frosting together.
Melted butter
Adds fat for a smooth, spreadable texture and a richer mouthfeel.
Orange juice
Moistens the sugar so it can form a spreadable paste, adding acidity and flavor.

The step that matters

Beat until just stiff enough to spread. Sugar sets firm as it cools and thickens, so overbeating or adding too much liquid can make the frosting runny or stiff and grainy. Stop once it holds its shape and spreads easily.

Swap the orange

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

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

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