Royal Icing Recipe
(slight adaptation of Antonia 74 Recipe)
5 TBSP meringue powder
1 tsp cream of tartar
6 oz warm water (3/4 C)
2.25 lbs powdered sugar (roughly 8 C or a 2 lb bag works)
generous tsp of corn syrup (I use less in humid areas)
1 - 2 TBSP emulsion or extract of choice
In mixer bowl, pour in the warm water, meringue powder, and cream of tartar. Mix it with a whisk by hand until it is frothy.
Pour in all the powdered sugar and mix on lowest speed using the paddle attachment for 10 minutes. Scrape down the sides after the first couple of minutes to make sure all sugar is incorporated and there are no grainy bits.
Add corn syrup and emulsion during the last couple minutes of mixing.
The frosting should be thick and creamy with stiff peaks. Use it immediately or place in a container with a tight fitting lid as it dries fast. There is no hard and fast rule about how long it stays fresh, but it will separate and need to be re-mixed. Some decorators freeze leftover icing with great results.
A great place to get LorAnn brand emulsions is Ross Dress for Less in the kitchen section. There are many fun flavors and now Michael's is carrying some as well. You can always find them online as well.
After mixing, slowly add the water to get a flood consistency. It's easier to add more water than to re- thicken your icing.
I color before I thin, that way if I want a piping consistency and a flood, they will be a perfect match if I bag some for piping, then thin the rest for flood.
For flood, I use about a 10 - 12 second flood consistency: run a knife through the icing and count the seconds it takes for the surface to become smooth. You need to find the best consistency you prefer through practice.
For piping, I add just enough water so when I pull some up with a knife, the peaks barely fall.
- There are many variables when creating with sugar and weighing takes out some of the guesswork as you adapt it to better suit your conditions and to get the results you want.
