Offering maximum efficiency through modern technology, the d5 line from All-Clad bonds five distinct layers in a perfect harmony of cooking performance. The cookware features a patented three-layer aluminum and steel core that propels heat sideways, eliminating hot spots and driving through the entire pan, not just the base. The non-reactive stainless steel interior creates the optimal cooking surface, and the magnetic exterior layer is well suited to induction cooktops as well as traditional gas and electric stoves. The pans feature flared sides for easy pouring, and the stay-cool stainless steel handles are ergonomically balanced for reduced stress when lifting.
