Today is National Doughnut Day. You know what to do. I remember 70 years ago getting a “toasted doughnut” and a coke as a special treat at a downtown drugstore in Durant, Oklahoma, sitting in a booth with my mother and grandmother. To toast a doughnut, slice it in half like a bagel and put the cut side down in a skillet for a few minutes. Perfect plan for a day-old doughnut, although, seriously, who has leftover doughnuts?
