re: How to season Cast Iron skillets

Once a piece is fully cleaned and dried put it in the oven "naked"; no oil of any kind and heat it to 450°F. Leave it in long enough to just reach that temperature. Be careful and remove the piece from the oven and let it cool to where you can just handle it. This step works great for slightly darkening the peice and giving it a uniform appearance. No one likes a spotted or zebra stripped piece. Use Crisco shortening only and use a cotton rag (t-shirt) to apply a thin/very light coat on the entire piece. If there are tight nooks and crannies to fill in, use a Q-tip.

Once completely and lightly coated (note: we stress a LIGHT coat), put it back in the oven at 400°F for 30 (use a timer) minutes and at that point turn off the oven and leave it in the oven till it cools on it's own.

When you remove the piece it will have a nice dark brown uniform pantina that shines brightly.

You can repeat with one or more coats of Crisco, if you like, but you'll be happy none the less.
