  • Can I use a self-cleaning oven to strip a cast iron pan?

    The short answer is yes.

    The more complex answer is … maybe.

    A self-cleaning oven is the closest most of us have to a blast furnace inside of our homes. And as many people will tell you while there are multiple ways to strip old seasoning from cast iron, the high heat of an oven’s clean cycle might be the simplest.

    My oven claims that on self-clean mode the temperature gets to nearly 900 degrees Farenheit (or about 480 degrees Celsius.) That’s hot. Hot enough to incinerate the seasoning off of any pan.

    So what is cast iron seasoning anyhow that we can burn it off our pans, pans that we use over heat all the time?

    Cast iron seasoning is a layer of polymerized oil.

    Oil is a word we use to describe a vast variety of chemicals with complex molecular structures and specific physical properties. Cooking oils generally come from crop plants and we can eat them.

    Polymerizing is a fancy way of saying that many smaller molecules can be chained together to form one massive molecule. Plastic, rubber, nylon are examples of polymers you might be familiar with already. Cast iron seasoning is also a type of polymer.

    Cooking oil at the right temperature can be turned into a polymer onto many types of surfaces. We take advantage of this process to season cast iron cooking pans, covering them with lots of very large oil polymers that at the correct window of temperatures create a non-stick cooking surface. Simplistically, we are creating a kind of coating by linking uncountable small oil molecules together using heat.

    This coating improves and strengthens with just enough heat, but as with many types of natural compounds if we use even more heat we can destroy it too. By design, because we like to have clean things, it incinerates at the same temperature of other charred food bits, grease, and cooking stains… or the temperature a self-cleaning oven.

    So, yes, you can exploit the almost-blast furnace temperatures available in your kitchen to burn the polymerized oil layer from your cast iron pan and “clean” it bare in your self-cleaning oven. Almost 900 degrees Fahrenheit will reduce those polymerized oils to a fine ashy powder that you can wipe off with a damp cloth.

    The maybe part of this answer is that high heat is unpredictable. Even some of the best cast iron is not made as uniformly as it may appear as you heft that heavy pan onto the fire. Pans are meant to be heated and then disperse that heat in a specific way (into food, into the air, etc.) So when you heat a pan in very hot in contained space, in a way it was not designed to be heated, there is a chance it could crack or warp.

    I’ve personally stripped multiple pans by this method and never had a problem, but all of those pans were replaceable and inexpensive. If I was restoring something more valuable or an antique, I might not take the shortcut of a self-cleaning oven.

    So again, can you use a self-cleaning oven to strip a cast iron pan… maybe. This method is fast and convenient (especially if you’re already cleaning your oven) and you can start fresh with a bare metal pan. This might be worth the maybe.

  • Cast Iron Care Checklist

    Kinda surprising actually that I haven’t written on this topic yet, but here goes…

    If you’ve been thinking about investing in a cast iron cookware collection, your new pans and griddles need a small collection of tools to live their best life with you.

    As with many hobbies, there are expensive and cheap versions of available care accessories. Many companies will happily sell you branded tools, purpose-made implements, and specially crafted concoctions. Most of these items are important to care for your iron, but the pricy version of it is not. Cheap or free alternatives often exist. After all, cast iron cookware has been common for hundreds of years, but imported organic flaxseed oil probably has not.

    Ten of the tools I keep handy to maintain my cast iron collection are:

    Seasoning Oil – Personally, I lean heavily on canola oil for a post-cleanup wipe-down because we always have it in quantity and handy, but I also keep a bit of shortening or leftover bacon grease in the house for my purpose-seasoning efforts. There are numerous products on the market that are labeled as cast iron seasoning products (and I intend to buy some and try them) and many people online swear by flaxseed oil (but it is expensive). Whatever your oil of choice, this tool is a must for ongoing maintenance of your pans.

    Heavy Duty Paper Towels – If I’m feeling flush, and I happen to be near a hardware store there is a brand of blue, commercial grade paper towels that are just about perfect for cast iron clean up. If I don’t have these around, plain old paper towels are a must for our supply closet.

    Coarse Salt – The first time I tried it I was amazed by how much basic post-cooking cast iron cleanup could be accomplished with a quarter cup of water and a tablespoon of coarse salt. A few minutes of simple soaking usually means that with only salt and elbow grease I can clean up almost any pan. For anyone new to cast iron who is skeptical about the no-soap approach, try a salt scrub and your uncertainty will be alleviated.

    Stiff Bristle Brush – To help with the salt scrub (as above) a good brush is also a must. We use our Lodge-brand brush so much it rarely even makes it back into the drawer.

    Plastic Scraper – For slightly tougher clean-up jobs, I keep a couple of these in my collection. They are also invaluable for scraping out bits of set fat or other pan leftovers that don’t make it onto your plate, either by design or because you’re just too full to eat it.

    Chainmail Scrubber – An optional big gun in your arsenal in the war on pan clean up is a heavy-duty scrub pad. I rarely use this personally but for those deeply stubborn bits (or when I’ve let my daughter cook and there are bits of burnt food clinging to the pan) a coarse, seasoning-safe scrubber is worth investing in eventually.

    Heavy Duty Oven Mitt – It probably goes without saying, but the best way to use and care for your cast iron is to make it hot. Over a flame, from the oven, or atop a burner, you can neither use it nor care for it if you can’t touch it. Get yourself some serious mitts that will allow you to hold, lift, move, and carry a hot pan without grilling your digits.

    Storage Rack – Sure, you could stack your pans one on top of each other — like an animal! Or you could invest in an elegant way to give those pans a way to stack or hang in style. There is probably something to be said about preserving seasoning and preventing damage this way, but the simpler reason is that if you can access them, you can use them.

    Self-Cleaning Oven – A dual-purpose tool, a hot oven is vital for seasoning new pans or touching up the ongoing effort to keep your season even and strong. Additionally, a self-cleaning oven can get hot enough on the clean cycle to obliterate all the seasoning layers on a pan that needs a refresh. This is controversial and you shouldn’t do this with antiques or anything you can’t easily replace. Whenever we run the self-clean on our oven, I always toss in a pan or two that are starting to chip or build up seasoning in weird ways. This strips them clean and allows for start a fresh on bare iron.

    Fire – Heat is heat, but nothing beats cooking over real fire. Plus, if your pans could talk, they would thank you for the chance to touch some real flames. Not everyone has access to daily fire in the form of a gas stove or barbecue, but taking your pan to a campout or picnic with some burning wood is what your cast iron cookware was made for.

  • Dozens of Dozens of Sourdough

    I woke up at 6 am this morning to bake bread.

    It had been proofing overnight in my cast iron loaf pan, dusted with flour and lightly covered with a bit of plastic wrap to keep it from drying out for the twelve hour counter-top rise.

    It was the one hundredth and fourty-fourth loaf I’d baked since that first pandemic lockdown began back in March 2020. One dozen dozen sandwich loaves.

    Bread as far as the mind can see.

    A slice of sourdough bread rests on a cutting board.

    Had I not picked the “cast iron guy” as the name for this blog, a close runner up could have easily been something to do with sourdough.

    As much as countless people have jumped on the sourdough bandwagon during these times of COVID restrictions and being stuck at home needing something to do I’m going to claim early-adopter status and say I have been dabbling in sourdough bread for half a decade now. My interest sparked after reading a book by Michael Pollan where he discussed the history of fermentation and other slowish food preparation methods. My research didn’t end there, though, and after a couple false starts with starters, I gave rise to my current levain in early 2019.

    Yet a mere one year ago my two year old starter was nothing special. I’d been baking bread three or four times a month, usually when we needed a good dome loaf for a holiday or a party or to accompany a nice meal at home.

    Then about ten and a half months ago I got sent home from the office to “temporarily” work from home.

    On my drive the radio was talking about potential food shortages and the chance for panic buying as people stocked up for the long haul. I stopped and picked up a few groceries, including a big bag of flour. Upon arriving home I pulled the starter from the fridge to let it warm up for a batch of bread.

    I’d been tracking my bakes with sharpie tick-marks on the lid of the starter’s container, but I switched colours to track the loaves I was going to cook while the pandemic passed us by. The Kid asked me as I was weighing out the flour if I could make “square loaves” (instead of the usual domes) because it was easier for her sandwiches. We baked those first loaves the next day after a long rise in a pair of cast iron loaf pans. We haven’t really stopped. Multiple times per week fresh bread comes out of the oven, usually two loaves in a batch, and there is always fresh sourdough to be eaten on our counter.

    One hundred an fourty-four loaves later, a dozen dozens, sourdough has become our pandemic legacy.

    So many sandwiches, breakfast toasts, afternoon snacks, and heels turned into garlic wedges.

    A pair of pans.

    A tub of cultured flour, water and natural yeast.

    And one family fed on a reliable source of delicious bread.

  • Griswold Egg Pan (Part One)

    Some more backstory…

    Just before the pandemic rolled in and I was nursing ideas about how to make effective use of my domain name I struck upon the plan of buying and “restoring” old cast iron pans. My plan was to scour through eBay, adventure through yard sales, and bumble among the aisles of second hand shops to look for old pieces.

    I would buy them.

    I would clean them.

    I would re-season them and use them.

    I would write about them.

    So in September of 2019 I picked up the first of my project pieces from an online seller, a Griswold #3 Egg Pan which arrived in fair, but crusty condition, via the mail.

    A small cast iron frying pan on a cutting board.

    As is visible in the attached photos (the pan resting on a cutting board, snapped in September 2019 & after a light wipe down) the small pan needed a little bit of care. It was dirty for a start, as if the seller had cooked lunch in it, cooled it off, then packed it off to be shipped. Also, the seasoning had the chipped and peeling look of a wall that’s been painted a dozen times over the years and then started to erode and wear revealing the layers. Otherwise it’s a nice piece. There is some uneven casting on the bottom (and I have no means or skill to refinish this) but the cooking surface is smooth and clear of scars.

    First, a little about the history of a piece like this. I specifically went looking for a Griswold pan because there they are kind of the stereotypical antique but affordable collector cast iron piece, new enough to find in your grandparent’s kitchen but old enough to say, hey… this is an old pan.

    “Griswold Manufacturing was an American manufacturer of cast iron kitchen products founded in Erie, Pennsylvania, in business from 1865 through 1957. For many years the company had a world-wide reputation for high-quality cast-iron cookware. Today, Griswold pieces are collector’s items.”

    – Wikipedia

    I’m not a cast iron restoration expert.

    Over the last five years and in using multiple pieces of my (purchased new) cast iron cookware for that long, I would firmly tell you that as far as use and care goes, I’m in the intermediate “home cook” skill level.

    That said, a caveat. Restoration is a new hobby for me. In other words, I’m probably doing something wrong and I’m not going to be doing much in the way of repairs so much as this more about simple cleaning and re-seasoning efforts. So… be gentle in your replies. I’m learning out here in the public eye.

    Now, the Griswold #3 709 I is not a valuable collectors piece, but I think it’s at least sixty-plus years old. Tiny. Only about seven inches across, it makes for an ideal egg pan. I’ve been through a few forums and websites trying to put an age to it and as far as I can tell it was probably cast circa 1939-1957. Neither rare nor of import, I figured it was a neat first “old” piece to kick off my set, and I wouldn’t be destroying an historical artifact if I messed it up.

    My first step was to run it through the clean cycle of the oven. This stripped the iron down to bare metal. Then I cleaned the char and oxidized powder off with soap and water then immediately ran a couple seasoning cycles in a hot oven with a light vegetable oil.

    After it cooled I put it the cupboard …and forgot about it for a while.

    The next two pictures (on a granite countertop) were snapped in January 2021, as I pulled the piece out and decided to write a short series on this new blog.

    I ran it through another seasoning cycle (lightly oiling it and baking it with my latest round of sourdough bread).

    I cooked a couple eggs in it.

    I grilled a cheese sandwich.

    It’s starting to develop a useful and seasoned cooking surface.

    And as I continue to season and cook with this pan over the next few weeks and months I’ll write future posts with more info.

    Stay tuned.

  • Recipe: Cast Iron Campfire Waffles

    Even far from an electrical socket, when I wake up in the woods I still have a few morning rituals. I need my hot cup of coffee brewed in one of a variety of ways: steeped, perked, or filtered. I usually try to eat a piece of fruit to start my day off right. And then I set out to cook a hearty breakfast for myself and the family.

    Recently, and thanks to an amazing find at one of our local camping shops, that hearty breakfast has included fresh campfire waffles.

    Yes, waffles. Over the campfire.

    The easiest way to do set yourself up for campfire waffle success is by prepping some of your ingredients at home first.

    In a plastic zip bag at home mix:

    2 cups of flour
    2 tablespoons of sugar
    4 teaspoons of baking powder
    1 teaspoon of salt

    In a bowl at your campsite mix:

    1 bag of dry ingredients (as above)
    2 eggs
    1/3 cup of vegetable oil
    1 1/2 cups of milk

    Also, pack some extra oil for cooking and for caring for your waffle iron.

    My waffle iron needs about five minutes to heat up over a cooking fire after you’ve oiled it. Having a grate or other surface to rest your iron on is useful.

    When the iron is smoking hot (yes… literally smoking) open the iron wide (using heat-proof mitts) and add 1/3 cup of your waffle batter to one center of the grill plate. Close. Flip (and I do a gentle whirl to spread the batter out inside.) And return to the heat.

    Add a bit more oil to the iron between waffles.

    Figuring out when the waffle is done cooking without that handy beep of an electric iron is as much an art as a skill. Added to the complexity is that you’re cooking over a fire with irregular temperatures. Look for less steam. Look for visible doneness at the edges. Get a feel for the time it takes and be prepared to over/undercook your first couple waffles.

    Then… serve. Hot. Add fruit. Syrup. Whatever you like.
