National Hot Pastrami Sandwich Day is observed in the United States every January 14. This informal food holiday celebrates the hot pastrami sandwich, a classic New York deli item made from pastrami, which was introduced to the U.S. by Jewish immigrants from Romania and Bessarabia in the late 19th century. Pastrami is typically made from beef, although turkey pastrami is also popular, and it is prepared through a process of brining, drying, seasoning, smoking, and steaming. The sandwich is commonly served on rye bread and can be accompanied by coleslaw and Russian dressing in New York, or pickles and yellow mustard in Los Angeles. To celebrate this day, enthusiasts are encouraged to enjoy a delicious pastrami sandwich.
