Corned Beef of the World
In Ireland the classic is bacon and cabbage, not corned beef. Irish immigrants in New York swapped in the corned brisket sold by their Jewish neighbors' butchers, and St. Patrick's Day dinner was born. From there it went into the Reuben, the diner hash, Montreal's smoked meat and a can on every continent. Here is every style, step by step.

Irish Bacon and Cabbage with Parsley Sauce
The real Irish dinner behind America's corned beef and cabbage: a cured bacon joint simmered in a big pot, cabbage cooked in the salty bacon water, and a white sauce full of parsley.

Cork Spiced Beef
Cork's Christmas beef: a corned joint marinated for a week in allspice, brown sugar and three peppers, simmered gently, cooled in its liquid and sliced thin.

Corned Beef and Cabbage
The Irish-American St. Patrick's Day dinner: flat-cut corned beef braised low and slow in the oven, then cabbage wedges, carrots and red potatoes simmered in the strained, buttered cooking liquid.

Homemade Deli Corned Beef on Rye
Cure your own brisket for six days in a salt, sugar and pink curing salt brine, simmer it in a low oven, then slice it thin, steam it and pile it on rye with deli mustard.

Reuben Sandwich
Corned beef, Swiss cheese and quick-cooked sauerkraut on rye with a Russian-style dressing, griddled in butter until the bread is golden and the cheese melts.

Diner Corned Beef Hash
Leftover corned beef and diced potatoes, steamed tender in one skillet, partly mashed so they hold together, then browned hard in butter on both sides and topped with fried eggs.

Montreal Smoked Meat
Montreal's answer to pastrami: a whole brisket dry-cured for a week, soaked, crusted with pepper, coriander and dill, smoked low, steamed in foil until tender and piled on rye with yellow mustard.

Filipino Corned Beef Silog (Corned Beef, Garlic Rice and Egg)
The Filipino breakfast plate: tinned corned beef fried with browned garlic and onion, a mound of crisp garlic fried rice and a sunny-side-up egg.

Jamaican-Style Bully Beef
Tinned corned beef simmered with onion, tomatoes, sweet peppers, thyme, ketchup and a whole Scotch bonnet into a quick, peppery stew for rice.

British Corned Beef Hash
The British storecupboard supper: parboiled potatoes and cubes of tinned corned beef fried with onion, pressed into a crust, splashed with Worcestershire sauce and served with baked beans.

Sheet-Pan Reubens
Four Reubens at once in 30 minutes: quick sweet-and-sour cabbage instead of sauerkraut, a mayo-mustard spread, deli corned beef and Swiss on rye, baked on a preheated sheet pan so they toast without flipping.

Pastrami on Rye, Inspired by Katz's
Inspired by, not official: store-bought corned beef soaked to pull out salt, crusted with cracked black pepper and coriander, smoked low, finished in foil to 203°F and hand-sliced onto rye with mustard, the way Katz's Delicatessen serves it.
