One common trait among high-quality stainless steel cookware sets is that they are all constructed from non-reactive metals such as aluminum, and stainless steel. This means that food won’t pick up any unwanted flavors from your pots and pans when cooking. Non-reactive cookware is safe to use on gas, electric, and induction stovetops. Additionally, it’s usually coated with a material like porcelain to prevent corrosion on pieces that come in contact with acidic foods.
