Corned beef is made from the upper front leg of the cow, which is sometimes called “the beef brisket.” Pastrami can also be made from the “beef brisket,” but it does not have to be. You can make pastrami from another part of the cow, which is called the deckle or plate. Corned beef is often served with cabbage, or in a Rueben sandwich, which has corned beef sauerkraut, swiss cheese, and Russian dressing.
Pastrami is smoked meat, which makes it different from corned beef. Pastrami is usually eaten as a sandwich on rye bread with mustard. Both corned beef and pastrami are preserved through a brine solution, which is salt, and water combined.
From this process, you will then have to boil the meat. On the other hand, creating pastrami is different from corned beef. With pastrami, you need to coat it with peppercorns and then have it smoked.
