The Century paella pan by Pujadas is made of 99 ½ percent extra-strong aluminum for impressive performance. The aluminum provides excellent thermal conductivity and high efficiency, while the reinforced edges resist dents. The thick base prevents warping to maintain constant contact with the heat source for even heat distribution. A polished finish creates an elegant appearance and can prevent bacterial growth. The insulated stainless steel loop handles offer a cool, comfortable grip, while their strong rivets promise a secure connection. This NSF-certified Century saucepan is compatible with gas, ceramic, and electric cooktops.
