Have you ever made a home made vanilla cake, and frosted the cake with boiled icing? YUM! Except, when a 10 and an 11 year old aim to surprise the family with dessert by seeing a "7" instead of a "1" handwritten on the recipe card for the 'cups of sugar'. We poured that hot stuff over the cake, and what didn't soak into the cake formed a rather smooth outer 'shell' to the cake. When our mother came home she was none too happy to find her sugar all gone. She did insist we try to eat the cake. Over 40 years ago and we still laugh over that.
