Dixie Chocolate Icing

Ingredients

Directions

Make the icing

  1. Combine grated chocolate and evaporated milk in a saucepan; cook until melted and smooth, stirring frequently.

  2. Add sugar, corn syrup, and butter; cook until the mixture forms a soft ball when dropped in cold water.

  3. Remove from heat, add salt and vanilla, and let it cool in cold water until lukewarm.

Finish and spread

  1. Beat the mixture until it begins to set, then spread it on the cake.

  2. If the mixture sets too quickly, add a little cream or gently reheat it on the stove.

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

What each ingredient does

Bitter chocolate
Provides the chocolate flavour and the body of the icing.
Evaporated milk
Melts with the chocolate to make a smooth, creamy base.
Granulated sugar
Sweetens the icing and helps it set firm as it cools.
Corn syrup
Keeps sugar crystals small, giving a smoother, less grainy icing.
Butter
Adds fat for a richer, softer texture and smoother mouthfeel.

The step that matters

Beating until it begins to set. Sugar syrup crystallises as it cools and is beaten. Beating at the right moment makes the icing creamy and spreadable; beaten too late it turns hard and grainy, and too early it stays runny.
