The sandwich base pressure cooker:
It has a tri-clad base with a layer of aluminum sandwiched between two layers of stainless steel for even cooking and browning.
It’s actually a “Sandwiched base”. This means the heavy 3-ply or tripled layered base that is a feature of good quality pressure cookers. Usually, this applies to an inner core of aluminum that is surrounded by stainless steel — like the Allclad cookware line — although some brands opt for copper as the base, and many manufacturers use their own propriety trade names to describe this type of base.
Either way, the even heating properties of the heavy base insulates and helps to prevent food from scorching on the bottom. Used in modern pressure cookers with spring type valves, the 3-ply base helps retain heat, allowing us to use an extremely low heat setting and still maintain a steady pressure.
