The Long John is a bar-shaped, yeast risen, filleddoughnut often embellished with glaze or icing. In some parts of the United States[which?], unfilled bar doughnuts are called long johns and their filled counterparts are called éclairs. In other parts of the United States[which?], Long Johns are marketed as éclairs; the two pastries look similar but are created with different types of dough and fillings.
