Instructions

In a stand mixer bowl, whisk the confectioners' sugar and meringue powder.
Add the water, pistachio flavoring, and vanilla. Beat with the paddle on low speed until the icing is matte and holds stiff peaks, 7 to 10 minutes.
For outlining, use it as is or add water 1/2 teaspoon at a time until it holds a soft peak. For flooding, thin a portion until a ribbon drizzled on the surface disappears in about 10 to 15 seconds.
Keep the surface covered with plastic wrap or a damp towel while you work so it doesn't crust.
Let decorated cookies dry uncovered at room temperature until completely hard, at least 8 hours or overnight.

Tips

Grease breaks down royal icing, so use grease-free bowls and tools, and avoid oil-based flavorings.
Vanilla swap: use vanilla bean paste 1:1 in place of the extract for visible specks, or the seeds of 1 vanilla bean for each tablespoon of extract.
Best vanilla for this: Tahitian (floral, cherry, anise), or Madagascar (rich, creamy, classic). Any pure vanilla works.
Storage: Store icing airtight with plastic wrap pressed on the surface at room temperature for up to 1 week; rebeat before using. Decorated cookies keep airtight for up to 2 weeks.
