As the kitchen is the heart of your home, choosing the right cookware to create your culinary masterpieces is paramount. Stainless steel cookware is a popular option and for good reason: it is durable, easy to clean and allows for even heat distribution. But how exactly does stainless steel cookware work? In this blog, we will explore the science behind this kitchen staple.
Composition of Stainless Steel Cookware.
Stainless steel is fundamentally made up of an alloy that combines iron, carbon, chromium, and sometimes nickel. The most common type of stainless steel used for cookware is 18/10 stainless steel. This simply means that the steel is composed of 18% chromium and 10% nickel. The chromium is used to give the steel its resistance to rust and corrosion, while the nickel provides a lustrous shine that helps the steel stay looking great.
The Science of Stainless Steel Cookware.
Stainless steel cookware is often praised for being an excellent conductor of heat. While it may not be as efficient as copper or aluminium, stainless steel does a pretty good job when compared to other materials such as glass or ceramic.
The scientific explanation for this is that stainless steel is a poor conductor of heat. This may sound like a disadvantage but is actually a positive attribute for cookware. Stainless steel cookware heats evenly, meaning that the entire surface of the cookware gets heated. Additionally, it retains heat well, ensuring that food continues cooking even after it has been removed from the heat source.
The Importance of a Bonded Bottom.
One of the most important parts of stainless steel cookware is the bottom of the pan or pot. This is the part that comes into direct contact with the heat source, making it integral to how the cookware works. The bottom of stainless steel cookware is often made up of a series of layers to ensure even heat distribution.
The bottom layer is usually made from an aluminium or copper core which conducts heat quickly. The layer above that is stainless steel, which is added for its durability and resistance to rust. The aluminium or copper core is sandwiched between two layers of stainless steel to create a bonded bottom, which helps transfer heat from the heat source to the food.
Why Stainless Steel Cookware is Non-Reactive.
An important factor to consider when choosing cookware is its reaction to the food you are cooking. Stainless steel is non-reactive, meaning it will not leach any harmful chemicals or flavours into your food. This is due to the high concentration of chromium and nickel in the steel.
This property makes stainless steel cookware an excellent choice for preparing acidic foods such as tomatoes or citrus fruits. It will not impart any of its own flavours into your food, ensuring that the true flavours of your ingredients are preserved.
Cleaning and Maintaining Stainless Steel Cookware.
Stainless steel cookware is very easy to clean and maintain. The best way to keep your cookware looking its best is to avoid using abrasive cleaning tools such as steel wool. These can scratch the surface of the stainless steel and affect its ability to conduct heat evenly.
Instead, use a mild detergent and soft sponge to clean your stainless steel cookware. For hard to remove stains, try soaking the cookware in a mixture of baking soda and water overnight. The next day, gently scrub the surface with a sponge and rinse with warm water.
Final Thoughts.
Stainless steel cookware is a versatile and durable option for the kitchen. Its properties make it an excellent choice for cooking and a breeze to clean and maintain. Many manufacturers offer a range of cookware options, so whether you need a small frying pan or a large stockpot, there will be a stainless steel option that suits your needs. With its non-reactive properties, ability to distribute heat evenly, and ease of cleaning, stainless steel cookware is a must-have in any kitchen.
