We love Mauviel copper preserving pans -- so much, in fact, that they're all we use to make our jams! These pans are made in France, and are made of copper and hammered by hand. Their shape is perfect for quick moisture evaporation and prevents boiling over, copper provides even heat distribution and doesn’t react with the fruit-sugar mixture, and many people (including us) believe that the copper helps enhance the flavor of the jam.

We are pleased to offer the size we had in mind when writing the recipes in The Blue Chair Jam Cookbook, with a diameter of 14.17 inches and an 11.5-quart capacity. This size is what we recommend for the home jam maker. We also offer the larger 19.5-quart size for jam makers with more jars to fill!

For the home jam maker who is serious about taking their craft to the next level, we can recommend no product more highly than these Mauviel copper preserving pans!
