National Chocolate Éclair Day is observed in the United States on June 22 every year, celebrating the delicious pastry known for its smooth texture and rich cream filling. Éclairs originated in France during the 1860s, initially referred to as “petite duchesss” or “pain à la duchesss.” The name "éclair," which translates to "the flash of lightning," is believed to reflect either the glistening glaze of the pastry or the speed at which they are consumed. While éclairs are made with choux dough and filled with cream, some regions in the U.S. also refer to a different pastry, Long Johns, as éclairs; however, Long Johns are made with donut dough and filled with vanilla pudding or custard. This distinction highlights the diversity in pastry names and preparations across the country.
