You can certainly eat corned beef with boiled cabbage and carrots, but it can be a great deal more exciting to pile the shredded meat — ruddy pink, salty, fatty and meltingly sweet — into warm flour tortillas, then top it with a bright, crunchy, slightly fiery cabbage slaw. The contrast between the soft and the crisp, the salt and the sweet, is fantastic — particularly if you adorn each taco with a few pickled jalapeños and, perhaps, an additional swipe of mayonnaise. It’s not fusion cooking, nor appropriation. It’s just the fact that everything tastes good on a warm tortilla.
