Introducing the Jamie Oliver by Tefal Premium Cast Iron cookware range: cast iron cookware reinvented with a modern design to give today’s cooks a superior cooking experience. Both the round and oval stewpots also feature a condensation system in the lid: small spikes on the inside capture condensation and release it back on to food for incredibly tender results, every time you cook. The Oval Stewpot is ideal for slow-cooked roasts, stews and curries. The entire range has a matte black enamel exterior that really looks the business, plus an enamel interior that’s super easy to clean. You can use these pots and pans on any hob — even induction — and they’re ovenproof up to 250°C.
