To ensure evenly sized chunks, we prefer to purchase whole steak tips (sometimes labeled “flap meat”) and cut them ourselves. However, if you have long, thin pieces of meat, roll or fold them into approximate 2-inch cubes before skewering. (For more information, see related How-to-Cook.) Two and one-half pounds of blade steak can be substituted for the flap meat; if using, cut the steak in half and remove the gristle that runs through it. You will need four 12-inch metal skewers for this recipe. Our preferred brand of beef broth is Rachael Ray Stock-in-a-Box All-Natural Beef Flavored Stock. Prep-time include marinading time.
