I am using a cast iron pan and all of my pancakes are coming out like this. I leave them on and they get crispy on the outside and cook through but they do not brown. I tried turning the heat up and that just burns them in splotches. Then I tried a lower heat and they turn golden in weird uneven patterns but they still cook through. Ive tried different oils, no oils, reheating my pan, waiting longer before flipping (which causes the pancake to have poppled bubbles and dark spots instead of a smooth surface). And when I flip them, the second side gets sort of a film on it when I take it out of the pan, the outer layer separates from the rest (it kind of looks like saltine crackers lol) this is really frustrating. any tips?
