Royal Icing

Royal Icing Using Egg Whites:

2 large (60 grams) egg whites

2 teaspoons fresh lemon juice

3 cups (330 grams) confectioners (powdered or icing) sugar, sifted

Royal Icing Using Meringue Powder:

4 cups (440 grams) confectioners' (powdered or icing) sugar

3 tablespoons (30 grams) meringue powder

1/2 teaspoon extract (vanilla, lemon, almond)

1/2 - 3/4 cup (120 - 180 ml) warm water

Note: Food Coloring (I use Gel Pastes that can be found at cake decorating and party stores or else on-line)

Royal Icing with Egg Whites:

In the bowl of your electric mixer (or with a hand mixer), beat the egg whites with the lemon juice until combined. Add the sifted powdered sugar and beat on low speed until combined and smooth. The icing needs to be used immediately or transferred to an airtight container as royal icing hardens when exposed to air. Cover with plastic wrap when not in use.

Royal Icing with Meringue Powder:

In the bowl of your electric mixer (or with a hand mixer), beat the confectioners' sugar and meringue powder until combined. Add the water and beat on medium to high speed until very glossy and stiff peaks form (5 to 7 minutes). If necessary, to get the right consistency, add more powdered sugar or water. To cover or 'flood' the entire surface of the cookie with icing, the proper consistency is when you lift the beater, the ribbon of icing that falls back into the bowl remains on the surface of the icing for a few seconds before disappearing.

Makes about 3 cups

Tips:

For the right consistency to cover cookies, first test the icing by lifting your spoon and letting the icing drip back into the bowl. The proper consistency is when the ribbon of icing that falls back into the bowl remains on the surface for about 5 seconds before disappearing. Another way is to take a cookie and place a small amount of icing in the middle of the cookie. Using a small knife or spatula, push the icing to the edge of the cookie. If the icing runs off the edge, thicken the icing by adding a little more confectioners sugar. Do not add too much sugar at once. You want the icing to spread smoothly but don't worry about a few light streaks. They will disappear as the icing dries, and be aware that the icing can take several hours, or even overnight, to dry completely.
