Do you cook with a cast-iron skillet? Heat your skillet on low before adding your cooking oil. The food will stick less if the pan is heated first. When you finish cooking, remove food and debris from your pan. Add water between one half inch and one full inch deep. Heat on medium or low for 5 minutes to boil off any remaining food and grease. Discard the water. With a paper towel or cloth, rub cooking oil on the inside of your warm pan so that the entire bottom and sides are coated lightly. Now you're done. Use this simple cleaning process (water, then oil) to clean your pan every time you cook - it seasons your pan and makes it non-stick, the old-fashioned way!
