Pastry tins are specialized baking tools designed for shaping and baking various types of pastries. They come in different sizes and shapes, including round, square, and rectangular, allowing bakers to create a variety of desserts like tarts and quiches. Made from materials such as metal or silicone, pastry tins often have non-stick coatings to ensure easy release of baked goods. These tins typically feature a shallow depth, which helps in achieving a crisp crust while baking. Some pastry tins also have removable bottoms, making it easier to serve delicate pastries without damaging them. Using the right pastry tin can enhance the presentation and texture of baked treats.
