With this 10-pack of Wilko Multi-Purpose Roasting Bags, Sunday dinners will be tastier and less messy - the nylon-tie roasting bags seal in flavour, while helping to keep your oven clean. Suitable for use in ovens and microwaves, and freezer safe, the cooking bags are flammable and should be kept away from naked flames, electrical elements and the sides of the oven. They are not suitable for barbecues or grills. Care should be taken when removing the bag's hot contents. See packaging for directions for use and our cooking guide for standard ovens. Keep this product away from babies and children.
