Since cut-up beef is particularly vulnerable to bacteria, it should always be cooked to an internal temperature of 160F (70C).
To create stir-fry pieces yourself, cut beef in thin slices against the grain. Thin slicing is easier if you first put the meat in the freezer for ten minutes so it is partly solidified. For the stir-fry process, heat a small amount of oil in a wok or skillet over medium or medium-high heat and cook the meat in batches, stirring and tossing until the beef is no longer pink.
There are two methods for making stew. Brown stew calls for meat pieces that are first browned in oil. In "white stew" or blanquette, the pieces are cooked in liquid without the initial browning. Browning the meat caramelizes its outside surfaces, and is thought to give the stew a richer taste.
To brown-stew, heat a heavy skillet over medium to medium-high heat and add oil. Working in batches, brown all sides of pre-cut beef cubes. Add cooking liquid and seasonings and simmer until beef is fork-tender, 1 to 2 hours. To white-stew, simply skip the browning and cook the meat in liquid and seasonings until tender.
Cut beef into uniform cubes or strips. If using cuts from the round, marinate the cubes for several hours or overnight. Marinades are seasoned liquids containing tenderizing ingredients, either acidic foods such as lemon juice, wine, vinegar, and tomato juice, or natural tenderizers such as pineapple, papaya, or ginger. Place the kabob beef in an acid-resistant container and add marinade, about 1/4 to 1/2 cup (59.1-118.2ml) for each 1 to 2 pounds (0.45-0.90 kg) of meat. Turn to make sure marinade touches all the meat surfaces, cover, and marinate in the refrigerator for several hours or overnight. Marinades can be used in making sauce that will be broiled, but never consume marinades that have come in contact with raw meat unless they have been thoroughly cooked.
Thread kabob meat on skewers and place directly over the heat source. Grill 8 to 18 minutes, depending on the thickness of the meat.
