Can I use plastic bags to make a grill pan or roasting pan?

While it might be tempting to use plastic bags as a makeshift grill pan or roasting pan, it's not advisable. Plastic bags can melt or release harmful chemicals when exposed to high heat, which is unsafe for cooking. Instead, consider using aluminum foil or a proper metal pan for grilling or roasting. If you're looking for a disposable option, parchment paper or silicone baking mats can be used as they are heat resistant and safe for cooking.
