Using plastic wrap in place of aluminum foil for cooking is not recommended. While both can be used to cover food, plastic wrap is not designed for high heat and can melt or release harmful chemicals when exposed to temperatures above 350掳F (175掳C). Aluminum foil, on the other hand, can withstand higher temperatures without melting. For safety and to avoid potential health risks, it's best to stick to aluminum foil or other heat-resistant materials for cooking food.
