About the Recipe
A Few Elegant Notes
Consistency adjustments:
For piping, use icing at stiff-peak consistency.
For flooding, thin icing with small amounts of water (½–1 tsp at a time) until it settles smoothly in 10–15 seconds.
Corn syrup adds shine and helps prevent craters as the icing dries.
Always keep royal icing covered with plastic wrap touching the surface to prevent crusting.
Icing can be stored in an airtight container in the refrigerator for up to 1 week; re-mix briefly before using.
Clear vanilla keeps the icing bright white—regular vanilla may tint it slightly ivory.

Ingredients
5 tbsp meringue powder
1 tbsp light corn syrup
1 tsp clear vanilla extract
1 cup water
2 lbs. powdered sugar
Preparation
Step 1
In the bowl of a stand mixer, combine the meringue powder, light corn syrup, clear vanilla extract, and water.
Step 2
Using a hand whisk, mix until the mixture becomes foamy.
Step 3
Add the powdered sugar to the bowl.
Step 4
Hand-whisk until the powdered sugar is fully incorporated and the mixture looks soupy.
(This prevents powdered sugar from flying everywhere when the mixer starts.)
Step 5
Attach the paddle attachment and beat on medium-high speed for 4–6 minutes (level 4 on KitchenAid).
Step 6
The icing will thicken and turn bright white.
Step 7
Mix until stiff peaks form.
Step 8
Remove the paddle and gently wiggle it, the icing should hold its shape without drooping.
