A cooking technique involves frying food in hot oil to achieve crispiness. This method is used to prepare various dishes, including chicken.

Double-frying is a common approach, where food is first cooked at a lower temperature and then again at a higher temperature. This helps retain juices and creates a crunchy exterior.

Further details about this technique can be found in a cookbook called "The Chinese Way", which includes a chapter on frying methods and tips for achieving the right temperature, such as using a thermometer or a wooden chopstick.
