Both aluminium foil and butter paper (also known as parchment paper) have their uses in packing food, but they serve different purposes depending on the type of food and how it will be stored or cooked.
Aluminium foil is excellent for retaining heat and can withstand high temperatures. It's great for wrapping hot foods like grilled vegetables, roasted meats, or baked items. Foil is non-porous and can trap moisture, making it ideal for keeping food warm and moist.
Foil can react with acidic or salty foods (like tomatoes or vinegar), potentially imparting a metallic taste. It's also less eco-friendly as it’s not biodegradable and can be challenging to recycle if contaminated with food.
Butter paper is non-stick and is often used to line baking trays to prevent food from sticking. While it can withstand heat, it is typically used in baking at temperatures up to about 232°C. It is biodegradable and compostable, making it a more eco-friendly option.
A soft, bowl-shaped bread with a crispy edge, appam is made from fermented rice batter and coconut milk, ideal for pairing with vegetable stews or non-veg dishes.
Aluminium foil is better for retaining heat and moisture, making it ideal for packing hot, cooked foods. Butter paper is better for packing baked goods or items that must stay dry and crisp.
