Gingerbread Cookies: all-purpose flour ground ginger cinnamon baking soda ground cloves salt butter brown sugar egg molasses vanilla extract Royal Icing: confectioners' sugar meringue powder warm water corn syrup teal and green gel food coloring
Continue to mix on low-medium speed adding more warm water, one tablespoon at a time, to achieve the desired consistency. The ideal consistency is something that is a bit thicker than corn syrup.
Divide the icing into four separate bowls. Add food coloring to each of the bowls (except for one) to achieve the desired color. I used teal and green.
