The best beef steak cuts for slicing into strips for stir-frying include rump, rib eye/scotch fillet, sirloin/porterhouse/New York and oyster blade steaks. Add oil to the beef rather than adding oil to the wok – you’ll use less oil, and the meat will brown well. You can also add ingredients like a little soy or grated ginger for flavour. Use your fingers to massage the oil into the meat strips.
