The parchment round baking pads by Tala are made of silicone-coated paper - they do not stick to the tin or absorb fat, making them reusable. The circles are used to line the surface of a cake or cookie tin - they protect the surface of the tin itself and ensure that the cake will bake without the need to use fat to coat the tin.
Tala is a British brand that has been in existence since 1899. It is one of the most highly regarded British brands by chefs producing baking accessories.
