Many home cooks slice steak parallel to the muscle fibers, resulting in a chewy texture that resists your teeth. Flank and skirt cuts feature long, distinct grains running down the length of the meat. Position your chef knife perpendicular to those visible lines to shorten the muscle fibers before chewing. Rest the grilled beef for at least eight minutes under foil before cutting to retain internal juices.
Transforming cold leftover steak into taco filling requires gentle heat to prevent rubbery protein strands. Heat a cast-iron skillet over medium-high heat without adding extra oil until the surface reaches approximately 400 degrees Fahrenheit. Toss thinly sliced leftover beef into the dry pan for precisely 45 seconds per batch, stirring constantly until warmed through without additional cooking. Corn tortillas demand equal care; steam them inside a damp paper towel in the microwave for 30 seconds or brush them lightly with fat before toasting them on a hot griddle until pliable.
Street vendor traditions across Northern Mexico originally utilized inexpensive beef cuts cured in citrus juice before open-flame grilling. Acidic marinades containing lime and orange juice break down surface proteins during a four-hour resting window, though extended exposure past six hours will transform the exterior texture to mush. Layer the warm meat inside double-stacked corn tortillas to prevent tearing under heavy toppings. Finish the arrangement with finely diced raw white onions, fresh cilantro leaves, and crumbled cotija cheese.
