A brand new iron skillet requires simple care before you're ready to cook, and a few rules of maintenance in order to make the pan last forever (which it really can). Here are the things you should know:
Never put the pan in the dishwasher or run cold water on the hot pan. This can shock the pan and cause fissures or even warp the pan. After use, allow it to cool slowly before rinsing with hot water.
Iron usually takes a bit longer to heat than stainless steel, and it should be done slowly. Heat the pan slowly over heat and then adjust to your desired cooking temp.
The handles will become very hot! Use caution and always make sure you have an oven mitt or towels to cover the handles when you're cooking.
