Petits Fours Frosting - cooking recipe

Ingredients

1 cup white sugar
1 dash cream of tartar
1/8 teaspoon salt
1/2 cup water
1 drop red food coloring
1 drop green food coloring
1 drop yellow food coloring
1/4 cup confectioners' sugar

Preparation

Combine sugar, cream of tartar, salt, and water in a small saucepan. Cook to the soft ball stage, 234 - 240 degrees F (112 - 115 degrees C). Cool to lukewarm.
Gradually beat in enough confectioners' sugar to make mixture thick enough to almost hold its shape. Stir in flavoring. Divide into 4 parts. Leave one part white and tint other portions pink, yellow, and green.
To ice petits fours, place them on a cooling rack and spoon the icing/frosting over the top until covered.
