Backed by a lifetime warranty, Calphalon's Commercial Hard-Anodized Cookware is made to professional standards, offering the home chef unsurpassed cooking performance, superior construction and lasting durability. The 2.5-Qt. Shallow Saucepan with Lid is designed for making and reducing sauces, roux and for heating soup or, boiling eggs. The thick bottom and sides absorb heat evenly and help protect delicate sauces from overheating. The wider, shallower design allows liquid and moisture to evaporate more quickly, so your reductions and sauces are ready sooner.Each piece in the Commercial Hard-Anodized line is made of a heavy-gauge aluminum, all-metal construction with the advanced technology of the Cool V stainless handles. The aluminum construction provides superior cooking performance by distributing the heat evenly so there are no hot spots as you cook. And because it's made entirely of metal, each pan can be used in the oven and under the broiler. The hard-anodizing seals the cooking surface, making it stick-resistant and non-reactive to the foods being cooked. The Cool V handles are designed to stay cool on the stovetop, and are balanced with such precision that the pans feel lighter when you pick them up.
