In your bowl, mix the powdered sugar, merungue powder and water. Start eith a little water (5 tbsp), Mix until your icing peaks (7-10 on low or 10-12 on high)
Tap the bowl to get the air bubbles out and stir to release the bubbles
If you are coloring the royal icing, add it before you tap out the bubbles. Prep your piping bag, put in 3/4 of the way and twist
Begin with outlining your cookies then flood. Use the toothpick to gently release the air bubbles.
If you are dipping, do that instead of outlining.
Once you have your cookie covered, you can go ahead and paint (vodka and food gel) or add piped designes on top as just 2 of those fun options
