Corned beef originates from Ireland, while pastrami hails from Turkey and Romania, but they both use the same brine. Corned beef and pastrami can also be made from beef brisket, although pastrami is sometimes made from turkey, pork, or lamb. Different spices are used to flavor the two types of meat. They are also cooked differently, with pastrami being smoked and baked, while corned beef is boiled.
