To season a pan, preheat your oven to 300°F (150°C). Preheat the pan on the stove top. When warm, coat the inside surfaces of the pan with vegetable oil or lard. Continue to heat just until you see ripples appear on the surface of the oil. At this point, pour off any excess oil, give it a quick wipe with a folded paper towel held in a pair of kitchen tongs, and then put the pan into the oven for 45 to 60 minutes. Remove the pan from the oven and allow it to cool to room temperature.According to Yahoo!7:
