This classic two-part vessel belongs in any serious cook's kitchen. It's ideal for making delicate sauces such as hollandaise or for melting chocolate. Hewing strictly to tradition, the double boiler has a 3-cup insert of heavy porcelain and a 5-cup copper bottom pot with a thick, hand-fired tin lining (the artisan's brush marks are visible). The handles and the lid's knob are polished brass. Because copper conducts heat faster than any other cookware material (think copper electricity wires) and is so responsive to heat changes, adjusting heat quickly and subtly during sauce-making is a snap. You can also use the bottom pot as a small saucepan.
With its insert in place, the double boiler measures 8 inches to the top of the lid's knob and 5 inches in diameter. Though the copper comes highly polished, maintaining that gleam is not essential; cooks traditionally enjoy the patina age brings to copper as a sign that copperware is practical, not pretentious. --Fred Brack
