I have a cast iron dutch oven that needs to be seasoned, but I never really understood what it meant on how to season, or even how to properly clean it. Thankfully I found this great video from Crackle that leads the way. However video streaming is a bit choppy, so be patient.
An additional benefit is that the food cooked in a cast iron skillet absorbs the iron, which we need in our diets. Check out the brief note.
