Japanese Beef and Scallion Rolls

Blanch scallions in a pot ofboiling salted water 45 seconds, then transfer with a slotted spoon to a bowl of ice and cold water to stop cooking. Transfer scallions to paper towels to drain and pat dry.

Cut flank steak with the grain holding a large knife at a 30-degree angle to cutting board into 12 (1/8-inch-thick) slices (1 1/2 to 2 inches wide). Arrange slices 1 inch apart on a very lightly oiled sheet of parchment paper or plastic wrap, then cover with another very lightly oiled sheet of parchment or plastic wrap (oiled side down) and pound slices with flat side of meat pounder until about 1/16 inch thick.

Arrange 3 beef slices side by side on a fresh sheet of plastic wrap, overlapping slices slightly to form a 6-inch square with short ends of slices nearest you. Sprinkle square lightly with a pinch of salt, then lay 3 scallions (with some white parts at both ends) across slices at end closest to you and tightly roll up meat around scallions to form a log, using plastic wrap as an aid. Tie log with kitchen string at ends and where meat slices overlap. Make 3 more negimaki rolls in same manner.
