Can I use pure aluminum in baking or roasting food in a traditional oven or grill?

While pure aluminum is a common material in cookware, it's not recommended for direct use in baking or roasting food in a traditional oven or grill. Aluminum can react with acidic foods, potentially leaching aluminum into the food. Additionally, aluminum foil can burn and create a hazardous situation. For baking or roasting, it's safer to use materials specifically designed for these purposes, such as parchment paper, silicone baking mats, or oven-safe dishes.
