The gG Cast Iron Griddle: A Must-Have Tool for Every Kitchen The cast iron griddle is a classic, must-have, versatile kitchen tool. Like all gG cast iron cookware, this 10-in griddle is milled smooth & coated with 100% organic, fatty-acid-rich flaxseed oil, so there’s no break-in period. The nonstick cast iron pan is ready to go out of the box. We’ve also perfected the handle so you can maintain a comfortable grip while cooking. Plus, the absence of raised edges makes it effortless to flip, turn, and cook your food.
