- 1 large egg white*
- 1 1/2 cups powdered sugar
- 1/2 lemon, juiced and strained
Combine the egg white and powdered sugar in a medium-size mixing bowl and whip with an electric mixer on medium speed until opaque and shiny, about 5 minutes. Add the lemon juice and continue whipping until completely incorporated, about 3 minutes. The lemon juice whitens the royal icing. The royal icing should be light, fluffy, and slightly stiff. You may need to adjust the consistency by adding more egg whites if the icing is too dry or more powdered sugar if it is too wet. To make decorations, fill a cornet half full with royal icing and cut a small opening at the tip. Use the cornet to draw decorations.
*RAW EGG WARNING
Food Network Kitchens suggest caution in consuming raw and lightly-cooked eggs due to the slight risk of Salmonella or other food-borne illness. To reduce this risk, we recommend you use only fresh, properly-refrigerated, clean, grade A or AA eggs with intact shells, and avoid contact between the yolks or whites and the shell.
