How do you get a nice black patina on a cast iron skillet by seasoning?
I bought a 10 inch Lodge cast iron skillet the other day and I've been trying to season it, but I can't really get a nice black patina. Based on some previous postings on chowhound, I first washed the inside with some soap and scrubbed a bit. I could tell that some of the preseasoning was being washed off and the iron was being exposed. I then started scouring the inside with 100 grit sandpaper. More iron was being exposed, but it wasn't completely bare. I washed the skillet again and heated it on the stovetop to dry. I then added a light layer of extra virgin olive oil and baked it upside down in a 550F oven for several hours. I've been adding new layers of oil and baking for a few hours for the last 2 days. I've probably add about 8 layers. It's still going.
I checked this morning and the surface is shiny and not sticky, but it's still kind of brown. Through the surface, I can still see the iron that I had previously exposed by scouring.
Anybody have any suggestions?
It's going to take some time to build up the seasoning. Try cooking on it & forgetting about the soap and water! If it needs to be "cleaned" just use salt and oil in a warm pan - rub it around with a paper towel or cloth.
Suggestions for what? What are you trying to achieve by not following the manufacturer's directions?
For new cast iron I scrub off the pre-seasoning as good as I can
The pour in 1/8 inch cooking oil of any kind
Heat on low low flame for an hour or two
Every ten minutes swab some of that oil onto the sides for seasoning
Use a balled up newspaper for that
Let sit overnight for more oil penetration
Next day dump remaining oil and wipe clean with newspaper
Unfortunately deeper seasoning only takes place by cooking with it now
So use it
Do not clean with water
Keep it away from water!!!
Wipe clean with balled up newspaper
Sorry but newspaper is what you have to use until seasoning builds up
Brown paper shopping bags and clean rags can also be used. Old towel is very good
Animal fats will season cast iron quicker than sautéing vegetables
Thus, cooking hamburgers, bacon, chicken is helpful
Bacon grease is excellent
Cook just bacon in it and let the grease sit overnight
Next day heat up the cast iron and let grease cook in even more --say 30 minutes
Drain out all the hot grease and wipe clean with balled up newspapers
Sorry but no soap and water until seasoning gets set in
Even then never ever scrub clean with a metal pad under soap and water and dry it off immediately. Use plastic scubbing pad
Drying it off--- I would use an old towel dedicated for this purpose and don't use it on any other cooking pot
With the arrival of some brand new cast-iron in the place I cooked while in university, we went the bacon route. Cooked up a lot of bacon, served some, froze the rest. Used the rendered fat the next day to fry chicken. And that was that, those pans were all set. Pretty far from my normal fare, though.
Incidentally, we got the new cast iron because someone spent hours scrubbing all the old seasoning off the old ones. Then left them to dry with water in them. It still boggles the mind.
I'm shocked by some of this! I can't imagine why you would want to take the pre-seasoning off or why you would use sandpaper on a new cast iron pan; I don't think either of these actions is ever justified. In my experience olive oil becomes sticky; peanut or safflower oil is what I use. Don't use soap, but please do use water: it's impossible to get off stuck-on food otherwise. After every use, I boil water in the pan, let it cool slightly, rinse it off under the sink, scrub it with a stiff brush, dry it with a towel, and lightly oil it with peanut oil. This maintains a nice non-stick surface, and with use, over time it will become black.
I wonder if you followed the directions that acmorris suggested in another thread. Here's the thread: http://chowhound.chow.com/topics/433869
She/he seemed to have a very logical and scientific understanding as to what happens in the seasoning process, and talked about using olive oil at a high temp to season. I tried his/her suggestions with olive oil, and my seasoning began to flake off. I read that a couple others had the same problem. It's funny that acmorris doesn't post much, anymore, isn't it?
Anyway, I scrubbed that flaky seasoning off, and started over again. I used lard, and I baked it at 400 degrees, for an hour to hour and a half, and then let it cool. It was still brown, and I didn't know that it was okay, so I kept putting more layers on it. I now know that it's alright for the pan to be brown, at first. The more you use it, the better you patina will get. It will gradually get darker the more you use it.
I think that b/c I put too many layers on it, that it's beginning to flake off again, but only in the areas where there was excess oil while seasoning, so it's not too bad. I'm continuing to use it, and I think it'll get better. When I used the olive oil/high temp method the seasoning began to flake all over, and it was just not doable. It was as if the seasoning had become ash.
If you have to do it again, only put one layers of seasoning on. It won't be very nonstick at first, so you'll want to cook fattier foods on it, or foods that fry in alot of oil. Each time you use it, it will be reseasoning itself, and the seasoning will get better. Eventually, you'll have a nice patina, and the skillet will be pretty nonstick. After you achieve the nice patina, you can cook almost anything in it.
But this isn't true of Lodge pans, is it? They claim their pre-seasoning is soy based:
I assumed we were talking about these pans because they're the only ones I've ever bought new! Lodge only sells pre-seasoned cast iron these days, and I've never done more to a new pan than wash it with soap and water (the only time I use soap).
Most seasoning will start to flake when the pan is heated dry to a high enough heat, in which case you definitely need to scrub the pan well and re-season; so I feel your pain, amselby81. All I can say to acmorris is that olive oil has left my pans sticky, but peanut oil has never failed me. Lard and bacon grease are also excellent options, as you observe.
I sand new pans. It gives a better finish. I don't set about taking off the pre-seasoning but much comes off.
I then wipe the pan down with oil (olive or similar... I don't have a wide variety of oils on hand) and heat. I keep it wiped down and heated for a while and then use. I do that in the oven if I can but stove top is fine too.
The last pan I bought was a smallish lodge a few weeks ago. After sanding and stove-top seasoning it now has a grayish brown patina... no bright metal showing but the seasoning is pretty thin in places.
How does it work? Well, a few days ago I went to fry an egg and forgot to oil the pan. Realized my mistake just as I dumped the egg from its shell... but it fried just fine. No sticking, no mess, it cooked perfectly, flipped perfectly, and came out of the pan perfectly.
I normally add a bit of cooking spray if I'm cooking lean foods. After a while the patina builds up but the pan does NOT need to be black to work properly.
