Versatile not just for roasting joints of meat, Bakewell's oven bags are suitable for cooking pretty much anything and because the bag keeps all the juices and steam inside as foods cook, your meal will cook up to 10% faster than a traditional roast, saving energy as well as time. Conventional roasting, place it in the bag and close up with one of the ties provided, then snip the top corner off the bag to act as a steam vent and away you go. 100% recyclable PET - naturally bpa free.
