Apparently, the best icing for sugar cookies. It hardens nicely so you can stack cookies but doesnt get hard like a rock, so you wont hurt your teeth. Its very tasty too and you can add different extracts to change the flavors. ***1 cup powder sugar (confectioners sugar) **1 tablespoon milk ** 1 tablespoon light corn syrup ** 1 drop lemon juice (can be fresh) This will outline and fill approximately one dozen cookies in one color. Better than royal icing???
