Yes, another Julia post. This story continues to unravel revealing new layers like an onion. Julia's editor Judith Jones has a blog relating to cooking and her life in food/publishing. Copper pots are not very common to find when out shopping. Only place I find Mauviel cookware is at Williams-Sonoma and they are joined together with chains to prevent theft. Copper cookie cutters are the extent of my copper cookware/tools.

A copper beating bowl would be fun to have to beat egg whites to perfection in. To keep the copper exterior looking new, use a copper polish or a combination of lemon and salt. Martha recommended using Red Bear Copper Cleaner to clean the copper cookie cutters she once sold through her now defunct Martha By Mail division. Another method, which I have not tried, is to use cheap ketchup with a couple of other ingredients to bring back a gleaming finish. The sticker shock and up-keep prevents copper from being as popular as the enameled, cast iron Le Creuset pots or the much less expensive alternatives by Martha Stewart sold at Macy's.
