The slope-sided Sauce Pan or, as it is classically called, a Fait Tout, with its larger surface area, excels at reducing liquids and can be used for nearly any task.
If you have not cooked with 'real' Copper Cookware before, you'll be amazed by how quickly and evenly the pan heats up. This same property allows the pan to respond just as quickly to a reduced temperature setting if the pan is too hot. The superior thermal properties of this Copper Pan make it ideally suited for long simmers.
