Each year on the first Friday in June, people participate in National Doughnut or Donut Day. This day celebrates the doughnut and honors the Salvation Army Lassies, the women that served doughnuts to soldiers during WWI.
In 1917, the original “Salvation Army Doughnut” was first served by the ladies of the Salvation Army. It was during WWI that the Salvation Army Lassies went to the front lines of Europe. Home cooked foods provided by these brave volunteers were a morale boost to the troops.
The doughnuts were often cooked in oil inside the metal helmets of American soldiers. American infantrymen were then commonly called “doughboys.” A more standard spelling is donut.
