Nigella Pans have just the right thickness for optimum performance. They are 2.6mm thick to balance between strength and functionality. They feel nice and heavy in hand with ergonomically designed die-cast handles. A layer of aluminium is sandwiched right through, even at the sides, between two layers of high-grade steel: superior food-grade 18/8 stainless steel on the inside and 430 magnetic stainless steel on the outside, making the pan highly heat conductive and induction friendly. The thick base ensures the food does not get burnt and the 3-ply walls ensure even heat distribution throughout. The lid is also made of 304 Stainless Steel The brushed-finish interior retains the same look for a long time even after repeated use while the mirror-polished exterior looks classy and is easy to clean. The steel never tears, literally lasting a lifetime.
