The surface of our cast iron skillet is rough. If you look at a new lodge skillet, it is also rough. I've seasoned it about 20 times and stuff still sticks. If I can get the temperature just right, stuff won't stick, but that perfect temperature is hard to hit! I was visiting a neighbor the other day and they had a super old skillet. It had a very smooth surface. As an experiment, I want to make the surface of my skillet smooth. Any suggestions on how I might do this? I've mulled it over a bit and the best I can think of is to get some emery paper and just rub, rub, rub by hand.
