Kelsey's favorite kitchen essential takes center stage -- the cast iron skillet. It's so versatile, it works magic in the oven or on top of the stove. Cumin Scallops seared to perfection for Tacos With Tomatillo Guacamole, crispy-bottom Skillet Corn Cakes With Bacon and Skillet Blueberry Cobbler -- all prepared in one essential pan. Kelsey's Cast Iron Skillet rules!
