Boiled Frosting


  • 3/4 to 1 cupful sugar
  • 1 teaspoonful vinegar
  • 1 teaspoonful flavoring
  • 1/3 cupful water
  • 1 egg white
  • salt


Mix the sugar, water, and vinegar in a saucepan. Cook gently until the sirup (when dropped from a spoon) "spins a thread" 3 inches long. Remove from the fire, and gradually pour the sirup over the egg white to which a pinch of salt has been added and which has been beaten stiff. Continue to beat the mixture; when it begins to stiffen, add the flavoring, and spread over cooled cake.

The less quantity of sugar produces a more delicate and less dense frosting than the greater quantity.
