Cost, ease of maintenance, metal type and shape are all important considerations when shopping for commercial cookware. The metal type will determine the weight of the pan, its heat retention and whether it is corrosion- and rust-proof. The most important thing is to choose a pot or pan that your chef and kitchen workers know how to work with.
Commercial cookware comes in many metal types. The three most common are aluminum, cast iron and stainless steel. Aluminum transfers heat well, weighs very little and is the most economical metal choice. However, acidic foods like tomatoes will corrode the aluminum over time. Stainless steel is more high end. It is durable and easy to maintain, but does not transfer heat as well as aluminum. For this reason, many stainless steel pots and pans have aluminum bottoms to encourage even heat distribution. Non-stick pans with a Teflon coating are also available, although in recent years concerns have arisen about the safety of cooking with Teflon, since it may have trace amounts of the chemical PFOA, a likely carcinogen.
Cast iron is heavy, low-cost and favored by many chefs because it absorbs flavor over time and transfers it to cooked foods. The downside is that it is difficult to clean and prone to rust. No matter what kind of commercial cookware you choose, make sure to maintain it properly. Wait for aluminum and stainless pans to cool before cleaning, otherwise they could warp with the rapid temperature change. Also be sure to care for your stainless by avoiding harsh cleaning pads or corrosive chemicals like chlorine. Cast iron cookware should be regularly seasoned by coating it in oil and baking it for 45 minutes. It should be cleaned with soap but should never be soaked in soapy water, since it can rust or absorb the flavor of the soap.
Reducing preheat times, properly ventilating and loading foods efficiently all contribute to a greener commercial range. Check here for some valuable maintenance tips to help you get the most from your range.
