i just bought a new lodge crepe pan to make pancakes. when i do little pancakes (three little ones will fit on the pan), the pancakes will only brown toward the center of the pan. if i do one big pancake in the middle of the pan, the entire pancake browns. why do the edges (like 2 inches from the side) not get as much heat? isn't cast iron supposed to conduct evenly? would a more expensive cast iron pan behave the same way? i am so disappointed!
