Final answer:
The method used to fry fish involving breadcrumbs and high temperature oil is called deep frying. It involves submerging breaded fish into hot oil for a quick cook and a crispy outside with a tender inside.
Step-by-step explanation:
We fry fish using the deep frying method: breaded with crumbs at a very high temperature. This technique of cooking involves submerging the food item, such as fish, into hot oil, which is usually maintained at a temperature between 350°F and 375°F (about 175°C - 190°C). Coating the fish in breadcrumbs not only adds flavor but also provides a protective layer that helps to seal in moisture, resulting in a crispy exterior and a moist and tender interior. This method is widely used because it quickly cooks the food and yields a distinct texture and taste.
