The professional 40cm roasting tray is made from heavy-duty 18/10 stainless steel. It’s certified for professional use and designed to last a lifetime. It’s the largest size that you can buy that fits into a UK oven. It comes with a self-basting scissor rack, adjustable in 6 stages from flat to ‘V’ shaped. And, because your meat is raised on the rack, and your potatoes and parsnips sit underneath, you can typically fit in 50% more food than an ordinary roasting tray of the same size. Guaranteed for 25 years.
