One of my favorite things to take to a Pot Luck is a Spice Cake with Peanut Butter Frosting. (I actually had two potlucks to go to today.) (I love Pot Lucks, so this was pretty cool.) But back to my point......A good Pot Luck should have no duplicate dishes. I have a foolproof way of insuring that I don't bring the same thing as anyone else. It's the odd combination of Spice Cake and Peanut Butter. But today, I was stunned - stunned, I tell you, when an elderly lady came up to me and told me this was her brother's favorite dessert. How could this be? She had spent her life in Oklahoma and I had spent mine 1500 miles away. I asked her what her ancestry was - she said Cherokee, German, and Irish. I was about to give up finding a connection, when she said, oh, and my grandmother was full blooded French. Does Peanut Butter Frosting sound like a French thing to you? Me neither. Unless, of course, it started out as Almond Frosting and unable to get almonds, both our families substituted Peanut Butter. Marzipan Frosting on a Spicy Fruit Cake is not an uncommon dessert for a European.
