This 3.5-qt. Mauviel Sauce Pan is perfect for making stock, cooking beans or heating leftover soup. It's also great for steaming moderate portions of vegetables or creating sauces. It's crafted from copper and has a stainless steel interior that won't interact with foods and makes for easy cleaning. Copper is a terrific choice for cookware because it is twice more conductive than aluminum and ten times more conductive than stainless steel. No wonder copper is the most preferred material of cookware by popular chefs and avid home cooks; its ability to heat up evenly and rapidly and to cool down just as quick allows for maximum control and excellent cooking results. Its tight-fitting lid seals in flavors, moisture, and nutrients, making your food extra tastier! Please handwash with mild dish soap. Made in France. The Cuprinox cookware line features an extra-thick 2.5mm copper exterior and includes a thin layer of stainless steel on the interior of the line's pots and pans. The stainless interior resists sticking, doesn't react with acidic foods, and cleans easily with a sponge. The cookware also offers durable handles anchored with rivets that hold up to heavy use. Mauviel, a French family business established in 1830 and located in the Normandy town of Villedieu-les-Poeles, is the foremost manufacturer of professional copper cookware in the world today. Highly regarded in the professional world, with over 170 years of experience, Mauviel offers several different lines of copper cookware to professional chefs and home cooks that appreciate the benefits of their high quality products.
