Liquid cooking, such as saucing, is a task tin-lined copper is uniquely (some might say profoundly) well-suited to, and the copper saucepan is the mark of excellence in any batterie de cuisine. Copper's ultra fine heat distribution results in continuous, even currents inside the pan so starches and flavor elements do not settle out, adhere, over- or undercook, even in the lowest and longest of simmers.
When we started BCC, saucepans were our best-sellers by far for these and other good reasons. Our new versions are in even US quart capacities, much more stoutly constructed and, well, just utterly beautiful.
