There is so much to like about German Sandwich Day, which falls on September 25, that we must face up to the fact that — try as we might — we could very well run out of superlatives to properly describe the celebration. But where, oh where, shall we begin? With an appetite, of course! And with the basics — which means a quick look at the inspiration for this observance, an item both beautiful and delicious in its simplicity: the Butterbrot — which means “butter bread” in German. The Butterbrot is just as it sounds: butter with bread. And it’s eaten at any time of day — most especially on German Sandwich Day.
