把牛排切成片。 把糖、玉米淀粉，酱油，米酒和蒜末这五种材料一块在一个配有盖子的大碗里。 把牛排浸泡在腌汁中。

Slice the meat into 1/4-inch (6.35-mm) strips, cutting it against the grain.  If the resulting strips are still larger than bite-size, cut them in half to divide the length. The grain refers to the direction in which the muscle fibers in the beef are aligned, and it can be spotted by examining your steak for fine lines. Cutting with the grain means will result in tough, stringy steak, while cutting against it will make the steak more tender.  If you cannot find flank steak, look for top sirloin,
