Features cast aluminum construction with superior non-stick surface for perfect release every time. * Recipe included with pan. * For best results, brush a very thin layer of butter on the interior of the pan prior to each use. The butter guarantees perfect release and helps promote a smooth, tightly sealed crust, even browning and good flavor. * It isnt necessary to dust the pan with flour, which can produce an unattractive white crust on cakes and breads. * Clean with warm soapy water and soft dish cloth only.
