"[Photograph: Nick Kindelsperger] Recreating an authentic Italian beef at home sounds easy, but it's surprisingly hard to do without an industrial meat slicer. I don't know about you, but that's one piece of kitchen gear that I don't have. Fortunately, if you give up on roasting the beef yourself, there's another way. Why this recipe works: * Using thinly sliced roast beef from a trusted butcher ensures a tender Italian beef, solving the problem of slicing at home. * To make an extra beefy au jus, roasted beef bones and sautéed sliced stew meat are simmered for hours. * The thinly sliced roast beef warms in the au jus at 140°F, the ideal temperature for balancing tender texture without losing juiciness. Note: For best results, use high quality freshly-sliced roast beef from the deli counter...."
