Flash-fry is a cooking technique that involves quickly frying food in hot oil. Some synonyms for this method include searing, sauteing, stir-frying, and pan-frying. Searing involves quickly cooking food over high heat to brown the outside while keeping the inside rare. Sauteing is a similar method that involves cooking food in a small amount of oil over medium-high heat. Stir-frying is a Chinese cooking technique that involves cooking food quickly in a wok or frying pan over high heat. Lastly, pan-frying involves cooking food in a small amount of oil in a frying pan over medium-high heat, usually for a longer period of time than flash-frying. All these methods are great options for cooking fast and delicious meals.
