Tip: For pieces such as cornstick pans, muffin pans, or waffle irons, small pieces of stiff or corrugated cardboard are handy to work the seasoning fat into hard to reach areas. Dip an edge into the Crisco or oil, and poke it into the crevices. A cheap, natural bristle basting brush can also be helpful in "painting" seasoning fat or oil into the details of intricately-patterned pieces.
