The Wrong Coast
I grew up using cast iron. From my mom's skillet and dutch oven, to using my own as an adult.
The first thing I fried as a kid was potatoes in my mom's skillet.

I recently acquired a new CI skillet because my niece filched the old one I had. It's OK, I know where she lives, and I have high friends in low places that can offer some help. :sssh:
But the new pan being a different thickness and size, it's taken me a few passes to get used to it.
Which had me thinking; 'what are the do's and don'ts of cast iron pans?'

I'll share what I've learned over the years and hope that you all share your insights as well.
This by no means is definitive. As I've alluded to above, even different pans will require some getting used to and have their own way of serving us. My experiences will be just that, my own.

In no particular order: (this is dealing with skillets)
DO
  • Be patient. Let the pan heat up before starting to cook. Cast iron doesn't heat up evenly. You will get hot spots and cool spots on the cooking surface at first. Let it even out 5-10mins
  • Use the right temperature for the food. Too hot can make it stick or burn before its cooked. Too cool will cause the food to over-cook before it is browned. Veggies will be mushy, and proteins will be dry.
  • Wipe out any loose bits while the pan is still warm. Let it cool some and then using a paper towel wipe it clean.
  • Use hot running water in a sink to soften any stubborn bits. Use a wooden spatula, or soft scrubber to loosen them. Wipe clean
  • Dry thoroughly using a clean towel and place on the stove burner and heat until dry.
  • Take a paper towel with a few drops of oil (I use avocado and/or grapeseed) and wipe the cooking surface evenly and heat until it smokes. Let the pan cool.
DON'TS
  • Don't cook bacon in a new pan. In spite of what many say, bacon is notorious for sticking. Especially if not cooked properly, including regulating pan temps.
  • Don't use flaxseed to season a pan. It has a lower smoke point making it easy to polymerize, but it isn't durable and will crack and lift off the pan if used regularly.
  • Don't cook high acid foods on a new or newly seasoned pan. It will take some of your seasoning off of the pan. It's OK to cook tomatoes or use vinegar etc on maturely seasoned pans. Just add some more seasoning if needed.
  • Don't boil water in cast iron. Well, you can but it usually leaches the seasoning into the water causing it to turn black and adding whatever 'flavors' are in the seasoning to go into the water.
  • Don't be afraid to use a lid on your skillet sometimes. Sometimes you'll want the moisture/steam in your food to help with even cooking.
Random thoughts:
We don't season CI to make it non-stick. We season it to protect the pan from moisture and rust. It becoming nonstick is just a byproduct of that protection.
Food can still stick to a well-seasoned pan. Bacon is like that. Too high of a temperature can also make food stick. But that isn't always a bad thing. Stuck bits of protein can be used to make gravy/sauces right in the pan.

You can use any type of edible oil/fats to season cast iron. From lard/Crisco to olive oil to high smoke point oils like avocado but they are going to perform differently.
Some are more durable and last longer but can be harder to layer on the pan. Others will season more quickly but not last as long.
Some are neutral in flavor others will add some flavors. None are wrong, just know why you're using what you're using.
Several light layers are better than a couple of thick layers.

If you plan on storing your pan for a longer period of time (camping/RV), make sure it is cleaned well and seasoned well. DO NOT just rub some oil on it and call it good. The oil will go rancid and while that isn't the end of the world, it can ruin an otherwise good breakfast.

Thick pans retain heat longer than thinner ones. They are also less susceptible to cooler foods entering the pan. (they tend to stay at a more even heat)
I don't use dish soap to clean the pan unless I plan on seasoning it right afterward.
Most light plastic scrubbers or brushes work fine to clean with. I use my metal or wood spatula to scrape along the bottom of the pan while cooking to get most of it up.

I've had this new pan for a week. It was only lightly seasoned from the factory. Usable, but needs more seasoning. I've used it 5 maybe 6 times and the seasoning is already building nicely.

I personally will use the oven method of seasoning when I want to season the whole pan. Otherwise, I just use the stovetop burner to season the cooking surface.
As the seasoning wears off of the handle or the bottom from regular use, I'll season it in the oven again.

I like cooking eggs in cast iron. Always have. The only time I've ever had a problem with them sticking is when the pan was too hot, or the eggs are too cold.
Eggs are delicate and like to be fried at around 180*F (give or take- there's a window and it takes some practice)
I preheat the pan by turning the burner on med-high for a couple of minutes and then turning it off for a couple. This lets the heat even out thru' the pan.
Otherwise, it'll get too hot in the center and remain too cold on the edges. Too hot means the egg will stick.

Then I turn it back on to a medium heat.
While the pan is heating, I put some eggs in a bowl and fill with hot tap water. This quickly gets the eggs to room temp or at east takes more of the chill out. Less likely to stick.

Steaks are fun to cook in a skillet. I put the steak on the counter for at least 20mins up to an hour. Depends on the size of the steak.
I then heat the pan with just a splash of oil until it starts to smoke.
By this time, the steak has been oiled/seasoned and ready to add to the pan. I turn the heat down just a bit once the steak is in but keep it hot.

I also use a pre-heated meat press. Nothing fancy just an 8" circle of iron with a handle on top. Some like to rotate their steak several times, not me. I only rotate to sear both sides and the edges.

Plz add your thoughts and experience with cast iron. The pros and cons. Anything I haven't mentioned.

Happy searing!
 
Most modern dish soaps aren't that bad tbh. But it can take the surface layer off especially on newer/thinner seasoning.
It can also pick up some of the soap taste. Not a good thing.
 
I had a 12" wagner from the 60s (post 1960 "made in USA") that my niece pilfered. LOL I now have a new 10" that I'm breaking in. Great pan so far. But a little thicker than the wagner so it's taken me a couple of rounds to get it nailed.

But it's taking seasoning well and I'm enjoying using it. buying some steaks tomorrow.

Good tips BF.

Same applies with a new outdoor grill. My brother loaned me his old charcoal grill once. I cleaned it to look brand new. It took hours and hours. Man I was so proud at how shiney and new it looked.

He was mad at me. His wife was mad at me. His kids were mad at me. His dog was mad at me.

To this day I only use a grill brush to scrape away stuck on chunks of food.

I'll use cast iron outdoors but indoors it keeps setting off my smoke alarms. My kitchen does not have an outdoor exhaust fan. I season with corn oil.

You can find older vintage (and crusty) CI at rummage stores or garage sales. A trip to the sand blasters will make them like new again. Have the blaster use recycled garnet sand, it's powdery and leaves a nicer finish. This will make them like new again, and you can start the curing seasoning iron process with clean fresh metal.
I use cast iron every day, meat, eggs/potatoes, browning onions. There's nothing better!
 
I have a C.I. skillet, that no matter what I do- what ever I cook in it ALWAYS 100% of the time, the food sticks. I have watched TONS of videos by very smaht people , with them showing what to do and then them cooking on it and their food doesnt stick. Only thing I can figure is there is something inherantly worg with this skillet
 
What type oil are you cooking with?
In a well seasoned skillet I use a little spray olive or vegetable oil. Heavy cooking, in deep oil, I'll let soak in water sitting on stove. After cools off the remaining stuck fud wipes right off.
 
I recently acquired a new CI skillet because my niece filched the old one I had. It's OK, I know where she lives, and I have high friends in low places that can offer some help. :sssh:
Say the word, and I'll disable her fuse-box.
She'll have to call you, and rely on any flashlights you gift to her!

But seriously, fantastic topic. About 3 years ago, I took a serious interest in cast iron cooking, and acquired a couple of cast iron pots and pans. Was blown away the first time I learned I had to "season" a new one. You'd be surprised how many videos there are on YouTube that teach everything needed to know. Sadly, by the time I was done with my research, I realized that cast iron cooking just wasn't for me. Too busy with my two full-time jobs. And a surprising amount of work needed to get the best from cast iron cooking. But the cookware I bought, oh yeah; still have it.
 
As your pan is used more it will be less sticking. Try olive oil, healthier for you too👌 I use butter with my eggs, but veg or olive oil for most everything else.
I try to avoid seed oils when i can, but i will give the olive oil a try next time

Seen somewhere where most oilve oils are not so great ( a diluted mixture of other cheaper oils added in )
What brand are you using?
 
Wife uses cast iron. When I assist her, I just make sure there is plenty of oil to lessen sticking, though it seems that if one is pushing food around in the pan, the oil will also get pushed off spots and sticking will happen(?)

Temperature regulation (not too hot and not too cold) for the food you're cooking is very important.
Steaks at higher temps
Chicken at a little lower temp - you want it cooked thru but not over cooked
Eggs at an even lower temp - they're much more delicate.
Veggies will depend - like chicken, you don't want to over cook them and make them mushy before they're browned. but you also don't want them burnt before they're cooked thru'.

If you've been using teflon coated type pans, there'll be a bit of a learning curve.
My stainless pan have copper/aluminum sandwiched on the bottoms to help transfer heat evenly.
CI doesn't have that.

I prefer to let my food come up to room temp. (or at least get the chill of the fridge out of it) I don't want it 'shocking' the pan - the food will stick.
I also found that, depending on what you're cooking, you're going to need a little oil/fat of some type. I use different types for different foods to get different results. But any type works just fine for cooking.

Butter for flavor - There is water and milk solids/proteins in butter. Butter tends to burn easily unless it is properly clarified. Most of us don't bother with that, tho' I have before, so one has to keep the butter at a lower temp vs oils.
Olive oil for flavor - it has a higher smoke point vs butter. Virgin vs refined - refined has a higher smoke point if you're cooking foods that need a bit higher temp use refined vs virgin.
I like avocado oil when I want something neutral flavored and a higher smoke point.

When I cook eggs, I use butter. If I plan on cooking a bunch for a crowd, I might add a bit of oil to help keep the butter from burning.
Eggs are cooked at a medium heat. Too hot and they will stick always. I also let them sit in the pan without touching them. If the pan is within the right temperature, they'll release on their own.
But even in teflon pans they'll stick if the pan is too hot.

Another point to make is to let the CI pan heat up slowly (at least in a controlled manor) and sit at temp to even out. (usually turn the burner on med-high for a couple of minutes, then off for a couple, then back on to the setting I want to cook at and put the food in)
Cast iron takes longer to even out. It doesn't transfer heat like copper/alum does. Many stainless-steel pans have copper and/or aluminum sandwiched on the bottom. This helps with heat transfer and evens it out. CI doesn't have that. WE have to even the temps for the pan.

You must let it sit 'at temp' for several minutes to even out hot/cold spots. You can always turn the heat up once you start cooking if needed.
But it's important to let it heat up more slowly. Patience works for you here.

Keep practicing.

Thanks for the backup LOL We're on opposite coasts atm. She knows how I liked that pan. The problem was she did too...apparently more than me. LOL
I think this was her way of getting me to go visit more often. I don't mind that so much. She has a great family. Her husband trained as a SEAL here in SD (that's how they met) and is now living back in NYC and with the NYPD.

I found that if I had the time to use any fry pan, then CI wasn't any harder or took any longer to use. Different? Yes. AND there is a learning curve especially vs thinner teflon pans. So I do get that it isn't for everyone or always best to use.

I still use stainless (use all the time) and have an aluminum non-stick that I haven't used for a couple of years. Other family members use it when they visit.

One of the cooler side hobbies Gary 👍👍

> I had a super crusty iron skillet that was going to be a real fuss to clean,, so I tossed it in a hot bon fire for a while to burn off everything..
then after it cooled a bit, I reseasoned it good as new
Gotta say, rather entertaining night
 
I try to cook everything around 300 degrees, on ocasion 325 or seldom as high as 350
Thanks for all the info fellas esp. bluflaam777
