SUPPORTS EVEN STEAMING: The included clip-on lid stays secure during cooking and is specifically designed to allow excess steam and air to escape. This process is integral to achieving a moist, evenly cooked texture for traditional recipes like Christmas pudding, suet puddings, and sponges, preventing a dry or overly dense result. VERSATILE KITCHEN COOKWARE: Use this six-pack of 1 pint (570ml) basins for more than steaming. They are suitable for use in the microwave to heat food, in the freezer for storing leftovers, or as general-purpose kitchen containers. The durable polypropylene construction allows for repeated use, making them a practical addition to your baking supplies. FOOD-GRADE CONSTRUCTION: Manufactured from sturdy, food-grade polypropylene that is BPA-free. This material is chosen for its stability during the cooking process, ensuring the basin maintains its shape when subjected to heat from steaming or microwaving. The smooth interior surface helps with the release of your pudding after it has cooled. CONVENIENT MULTIPACK SET: This set includes six complete pudding basins and six corresponding lids, providing an ample supply for batch baking or preparing multiple desserts for gatherings. Each basin has a capacity of 1 pint (570ml), a standard size for many classic pudding recipes, so you can easily follow traditional instructions. SIMPLIFIES PREPARATION AND STORAGE: These reusable bowls are designed for preparing traditional steamed desserts. After cooking and cooling, the basins are also suitable for storing the finished pudding in a cupboard, fridge, or freezer until you are ready to serve, which saves you from needing separate containers for cooking and storing.
