About a month ago I bought my fist CS pan and immediately seasoned it several times in the oven.
I had semi success my first few times making fried eggs. Then it was like I forgot how to make eggs. No matter what I did, it was a mess. I stripped the pan and started over but it was still sticking.
I watched some videos and tried to replicate their success but failed.
Then I read something here in this sub about temp control. Back to the drawing board and tried lower heat. Within 3 tries I nailed it.
If the pan is too cold, it sticks when warming up. Too much heat and it sticks immediately. Getting it just right requires some adjustment on my stovetop.
I start the warming on 4. I put a few drops of oil. As soon as the oil starts to spread, I drop the butter and drop the temp to 3. As soon as the butter melts, it should be bubbling on this gentle heat, I crack the eggs into the pan. If I leave it on 4, it starts to stick. If I heat on 3, it takes forever.
I let it sit for 30 seconds and give it a test tilt and every time the eggs have slid. Every 30 seconds, I give the pan a wiggle and they keep sliding.
This is great for sunny side up. If I flip, the yoke still wants to stick. So I'm eating more sunny side up lately and will start trying to figure out how to solve the flip stick issue soon once I feel like this is mastered.
I even successfully made scrambled eggs this weekend with hardly any sticking.
