When using aluminum foil in the kitchen, it's important to avoid direct contact with acidic or alkaline foods as it may react and contaminate the food. Do not use it in broilers or ovens above 450掳F (232掳C), as it can melt and release harmful fumes. Avoid wrapping food in aluminum foil for extended periods, especially at high temperatures, as it may lead to the foil breaking down and leaching aluminum into the food. Always check for any tears or punctures in the foil to prevent food from coming into contact with the cooking surface directly.
