Foods taste much better when they are cooked in the copper pans. Copper cookware has an antibacterial effect too; germs and bacteria cannot survive on the copper surface. Usually copper pans are lining with a thin stainless steel to prevent copper reaction with acidic foods. The superior heat conductivity of copper guarantees to lock most water inside the food and as a result it causes a very delicious taste. Copper pans may be expensive, but it worths it and if they are cleaned properly they could last for a long time.
