What is "tin"?

Tin is a type of container made of a thin sheet of steel coated with a layer of tinplate, which provides corrosion resistance and a shiny appearance. These containers are commonly used in baking to shape and bake various food items, such as cakes, bread, pastries, and tarts. They come in various shapes and sizes, including round cake tins, loaf tins, and tart pans, and are valued for their ability to conduct heat evenly and create uniform baking results. Tin containers are often lined with parchment paper or greased to prevent sticking and ensure easy removal of baked goods.
