I like this icing because it avoids food dyes, but is easy, spreads smoothly, and has a slight sheen. For another au naturel icing that gives you green shades, check out my
green tea icing recipe here. The recipe makes enough to decorate at least 3 dozen 2¾ to 3-inch cookies. Since it is sweet, add just enough to cover each cookie; don’t pile it on. The recipe calls for meringue powder or egg white powder. Wilton makes a meringue powder usually stocked with cake decorating supplies. Some supermarket baking sections include dry egg white powder. If you can’t find either, you may leave it out.
