Cling film, also known as plastic wrap or saran wrap, has been a staple in many kitchens for decades. It’s used to cover food, prevent spills, and even cook certain types of dishes. However, there’s been a long-standing debate about the safety of cooking in cling film. Can you cook in cling film, and is it safe for consumption? In this article, we’ll delve into the world of cling film cooking, exploring its benefits, risks, and best practices.
What is Cling Film, and How Does it Work?
Cling film is a type of plastic wrap made from a thin layer of polyvinyl chloride (PVC) or polyethylene. It’s designed to be flexible, transparent, and airtight, making it an ideal material for food storage and cooking. When heated, the plastic wrap melts and releases chemicals that can potentially leach into food.
The Science Behind Cling Film Cooking
Cling film cooking, also known as “en papillote” or “al cartoccio,” involves wrapping food in plastic wrap and heating it in the oven or microwave. The plastic wrap traps moisture and heat, creating a steamy environment that cooks the food evenly. This method is often used for cooking fish, vegetables, and poultry.
Benefits of Cling Film Cooking
Cling film cooking offers several benefits, including:
- Even cooking: The plastic wrap ensures that the food is cooked evenly, reducing the risk of overcooking or undercooking.
