Here's a lovely, mouthwatering, aspirational upgrade for your kitchen on New Year's Day; something to use every day and hand down to your children: commercial grade copper pans with a thin stainless steel interior that provides a food-safe cooking surface without inhibiting the conductivity of the copper. This is the genius of copper: "Copper is fast and nimble. Its conductivity makes it sensitive to temperature changes, responding immediately when a cook raises or lowers heat, allowing you to precisely control the cooking process. It’s part of what chefs love about it. Said another way, it heats quickly and evenly, preventing food from sticking or cooking irregularly. These pans can handle the high heat needed for searing and browning flawlessly, or settle into a long simmer just as well."
