Kitchenware Minerals: Pots And Pans

Pots and pans are typically made from metals such as stainless steel, cast iron, copper, or aluminium. These metals all come from minerals. Stainless steel is made by adding chromium and nickel to steel, making it highly anti-corrosive and non-reactive. Copper is the best heat conductor of any material used to make cookware, but it is expensive and requires a lot of upkeep. Cast iron is a poor conductor of heat but is favoured for its durability and ability to withstand high temperatures. Aluminium is lightweight, sturdy, and fairly cheap, but it is soft and reactive, and can give food a metallic taste.

Stainless steel

However, one of the downsides of stainless steel is that it doesn't conduct heat very well, and the heat distribution is poor. Therefore, it is best to choose stainless steel pots and pans that have been reinforced with copper or aluminum. Higher-end cookware often uses 3-ply or 5-ply construction, meaning there are several layers of metal, which can also increase the weight of your cookware. Heavier stainless steel cookware generally means higher quality.

When purchasing a stainless steel pan, it is important to check that it is of good quality. Quality stainless steel cookware will not only produce better results but will also last much longer. To prolong the life of your pans, it is recommended to handwash them instead of putting them in the dishwasher, even if they are marked as dishwasher-safe.

Aluminium

To overcome these issues, some aluminium cookware undergoes anodization, a process that increases the thickness of the natural oxide layer, making the cookware harder, less porous, and darker. This type of cookware is known as hard anodized aluminium. It doesn't interact with sauces and is less prone to bending. Some aluminium cookware also comes with a non-stick coating, which makes cleaning easier.

Cast iron

To achieve a more even temperature distribution, cast iron pans should be heated slowly over an appropriately sized burner or in an oven. Due to their high thermal mass, cast-iron utensils can retain heat for an extended period, allowing them to continue cooking food even after the heat source has been removed.

In summary, cast iron cookware offers excellent heat retention, durability, and non-stick properties when properly seasoned. Its ability to withstand and maintain high temperatures makes it ideal for searing, frying, and long-cooking stews. However, cast iron's poor heat conduction can lead to uneven heating if not used properly. Additionally, cast iron cookware is heavy and requires careful maintenance to prevent rusting.

Copper

However, copper has its limitations. It reacts with the natural acids and minerals in food, so copper pots and pans must be lined with non-reactive metals like stainless steel or tin. Copper cookware is also more expensive compared to other metal utensils. It is also not suitable for induction cooktops and requires a lot of time and effort to polish and maintain its shine.

When it comes to choosing the right copper cookware, the thickness of the copper is an important factor. Copper cookware should be 2.5 to 3mm thick, which is the right range for both heat responsiveness and even heating.

Cleaning and maintenance are also important considerations for copper cookware. Copper develops a patina over time, which is desirable as it shows that the pan is well-conditioned. However, you want to avoid the grey-green verdigris, which can eventually blacken and rust. Copper cookware should be cleaned with hot soapy water and a gentle, minimally abrasive scrubber. For the exterior, you can mostly leave it alone or just wipe or rinse off any spills or drips.

In conclusion, copper cookware has its pros and cons. It is an excellent heat conductor, ensuring uniform cooking, and it adds beauty to your kitchen. However, it is reactive with certain foods, requires lining, and can be expensive and high-maintenance.

Carbon steel

One of the main benefits of carbon steel pans is their natural non-stick properties. However, this is only achieved through a process called seasoning, where heated oil is applied to the pan's surface to create a protective barrier. This process can be time-consuming and must be repeated regularly to maintain the non-stick surface. Acidic foods should also be avoided, as they can strip the seasoning.
