Why grease a baking tin?

There are several reasons why it's important to grease a baking tin before using it:

1. To Prevent Sticking: Greasing the tin creates a barrier between the food and the metal surface, preventing the food from sticking to the tin. This is especially important for delicate baked goods like cakes, cookies, and pastries that can easily break or tear when removed from the tin.

2. Even Browning: A greased baking tin helps to ensure even browning of the baked goods. When the tin is greased, it allows the heat to distribute evenly, preventing the food from burning in some spots and remaining undercooked in others.

3. Ease of Removal: Greasing the tin makes it easier to remove the baked goods after they are done cooking. The grease acts as a lubricant, allowing the food to slide out of the tin without breaking or tearing.

4. Clean Up: A greased baking tin is easier to clean after use. The grease prevents food particles from sticking to the tin, making it easier to wash and maintain the tin.

5. Rust Prevention: Greasing a baking tin can help prevent rust from forming on the metal surface. Rust can affect the appearance and functionality of the tin, and greasing it helps to protect the metal from moisture and corrosion.

It's important to note that not all baking recipes require greasing the tin. Some recipes, such as sponge cakes, rely on the batter to rise and cling to the sides of the tin for structure, so greasing the tin is not necessary. Always follow the specific instructions in the recipe you are using to determine if greasing the tin is required.
