How should I season brand new cast iron skillets?
Wash, rinse, and dry the skillets. Grease the inside of each skillet with solid shortening like you would grease a cake pan. Place in a 300-degree oven for one hour. Remove and cool. With use, the skillets may begin to look dry. When this happens, just wipe them with a light coat of vegetable oil. Cast iron improves with use. I have a cast iron skillet that I have been using for 35 years.
