A single-serving cheesecake, flourless chocolate cake or torte, released clean. The interlocking band hugs the smooth base for leak-proof baking, and when the cake has cooled a flick of the latch springs the sides open so you lift the band away and serve from the base. The pan is heavyweight European carbon steel with a PFOA-free non-stick coating and a reinforced beaded rim that keeps it from warping, oven safe to 450 F.
