Royal icing (for precise decoration)

Ingredients

Method

1. Beat egg whites or meringue powder
2. Slowly add powdered sugar
3. Beat 8-10 minutes until stiff peaks
4. Add vanilla
5. Add food coloring as desired

Two consistencies needed

Outline consistency

• Thicker, holds piped lines
• Take ribbon 10 seconds to disappear when dropped

Flood consistency

• Thinner, fills outlined areas
• Take ribbon 15-20 seconds to disappear

Method to use

1. Pipe outline around cookie edge
2. Let dry 30 minutes
3. Flood interior with thinner icing
4. Use toothpick to spread to edges
5. Dry 8-12 hours before decorating further
6. Add piped details after first layer dries

Simple glaze (easier)

Method

Colors

Food coloring

Christmas palette
