De Buyer Copper Conical Jam Pan 400mm

The De Buyer 400mm copper conical jam pan is a traditional piece of confectionery and preserving equipment, purpose-built for making jams, marmalades, and fruit preserves. Constructed from 1.7mm thick copper throughout, it follows the form that professional patissiers and preserving kitchens have relied on for generations — a wide, open conical shape that promotes rapid evaporation and allows easy working of the mixture.

Copper’s thermal conductivity is the key practical advantage here. It responds quickly to changes in heat, gives you a fast initial heat-up, and distributes temperature evenly across the base and sides. In jam making, where precise heat control matters and hot spots can cause scorching or uneven setting, that consistency is worth a great deal. The uniform wall thickness reinforces this, helping to avoid the localised overheating that leads to burnt fruit and wasted batch.

The conical shape serves a specific purpose beyond tradition. The angled sides allow you to work a stirring utensil right into the base and around the full curve of the pan, so the mixture moves evenly without sitting in corners. The flat base sits stably on a gas burner, which is the natural pairing for copper cookware.

• Even heat distribution helps preserve the natural colour and flavour of fruit
• Wide open shape accelerates evaporation for faster setting
• Responsive to heat adjustments, giving precise control over the cooking process
• Stable flat base suits gas hob use in professional kitchen environments
• Compatible with all heat sources except induction

This pan is best suited to patisserie sections, artisan food producers, hotel kitchens, and specialist preserving operations. It is not designed for high-volume continuous production — for larger batch work, a bigger capacity pan would be the more practical choice. Being copper, it will require appropriate care and is not suitable for induction hobs.
