Start by mixing the vanilla extract and water together.
In a stand mixer bowl, combine the sugar powder and meringue powder and start mixing on low speed for 1 minute.
Add the flavored water to the dry ingredients while the mixeris still on low speed. Once all the ingredients are incorporated, turn the mixer to medium/medium high speed and mix for another 5 minutes.
After the icing is mixed, set aside the necessary amount for coloring and cover the rest of the icing.
Add your gel food color, mix together then start to add water in small amounts to get the desired consistency.
Transfer to a piping bag and it’s ready for work!
Notes
The icing dries very quickly, so always keep it covered with a plastic wrap or wet towel.Unused Royal icing needs to be kept in an airtight container. That way, it keeps for a couple of weeks covered at room temperature.And one more thing, if you keep it for more than a few days, the water may start to separate from the icing. Just give it a good mix before using it again.
