What does it mean to line a baking sheet with aluminum foil?

Lining a baking sheet with aluminum foil is a common technique in baking for a few reasons:

1. Easier Cleanup:

* Aluminum foil creates a barrier between the baking sheet and your food, preventing messes and making cleanup a breeze. Simply remove the foil after baking and discard it, leaving your baking sheet clean.

2. Prevents Sticking:

* Some foods tend to stick to the baking sheet, even if it's greased. Aluminum foil provides a non-stick surface, ensuring your baked goods come out intact.

3. Even Heating:

* Foil reflects heat, which can help distribute heat evenly across the baking sheet, resulting in more consistent baking.

4. Protects the Baking Sheet:

* Foil can protect your baking sheet from scratches, especially if you're using abrasive cleaning methods.

How to Line a Baking Sheet with Aluminum Foil:

1. Cut the Foil: Cut a piece of aluminum foil slightly larger than the baking sheet, leaving about 1-2 inches of overhang on all sides.

2. Place on Baking Sheet: Carefully place the foil on the baking sheet, making sure it's smooth and even.

3. Fold Overhang: Fold the overhang around the edges of the baking sheet to create a secure barrier.

Important Considerations:

* Grease the Foil: For best results, lightly grease the foil with cooking spray or butter to prevent sticking.

* Avoid Using Foil with Certain Foods: Don't use foil for acidic foods (like tomatoes or lemon juice), as it can react with the aluminum and affect the taste.

* Proper Disposal: Discard used foil in the trash, as it cannot be recycled.

By lining your baking sheet with aluminum foil, you can enjoy easier cleanup, prevent sticking, and ensure even baking.
