Cook in style with this on-trend copper casserole dish from the John Lewis Croft Collection. Not only does copper add colour to a kitchen, copper cookware provides incredible conductivity. This range of lidded pans meets professional standards thanks to its triply construction: the outer layer of solid copper, an inner layer of stainless steel and an aluminium core (extending from the base of the pan to the rim) result in even heat distribution throughout the pan. This means no unpredictable hotspots or burnt edges, which makes warming liquids so much less fretful. Sturdy, stainless steel handles stay cool and are firmly riveted in place providing strength and durability. Suitable for all hobs, including induction. To add to the casserole dish's charm, the copper has a classic look that's too attractive to store behind cupboard doors. Copper can darken over time due to the natural oxidisation process, so use copper cleaner to polish the exterior and hand wash the inside. Croft Collection celebrates authenticity and craftsmanship with beautiful, considered pieces that are made with integrity. Its soft palette is enlivened with honey accent tones, evoking a relaxed feel you'll love to come home to forever. Getting the most from your induction pans All of our John Lewis induction pans are tested to the British and European standards for safety and performance. To ensure the functionality of induction pans, it is important to make sure the magnetic circuit with the hob isn't broken by: Making sure the size of the pan base is no smaller than the hob and ring Using pans with a flat base Not lifting the pan off the hob top continuously Giving coated and aluminium pans with steel bases more time to heat, as the aluminium sides do not heat directly from the hob
