What is the best way to season a cast iron pan?

The best way to season a cast iron pan is to start with a clean, dry pan, then apply a very thin layer of a high smoke point oil like flaxseed, vegetable, or Crisco all over the surface, including the outside and handle. Wipe off as much oil as possible so only a barely visible layer remains, since too much oil causes sticky buildup. Place the pan upside down in an oven at 450 to 500 degrees Fahrenheit for one hour, then let it cool in the oven. Repeat this process three to six times to build a strong, durable seasoning. Cooking with oil regularly afterward continues to improve the surface over time.
