- 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
- 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.
