One of the beautiful things about using stainless steel cookware is the fact that food can stick to it.
I know, it sounds weird but this is not a bad thing. Before I got into cooking a bit more seriously, all I ever used were nonstick pans. It felt safe! A pan to which food would stick to was the equivalent of game over. Impossible to clean pans. Destroyed food. Burnt bits etc, etc, etc… horrid.
Today, I don’t think I have a single nonstick pan at home and I actually look forward to using pans to which food can stick to… sticky pans.
The little bits of food that stick to the bottom of a pan (fond) as they brown are the key to some really cool flavour development techniques. All that beautiful browned stuff can be deglazed by using any liquid and the result is pure delicious edible gold, but I will dedicate a post to talk about that. in the future Today’s post is about the opposite. How to make your stainless steel pans nonstick.
So how should we cook something that shouldn’t stick to my “non-nonstick” pan, something simple like an egg?
Things can go south pretty quickly. Trying to retrieve that egg can very easily end in disaster with half the egg glued to the pan and the other laying shredded all over your counter and some of it on your spatula.
The cool thing is, any stainless steel pan (any metallic pan really) can be made virtually nonstick. It’s the same concept behind seasoning cast iron cookware. By heating up oil in the pan and allowing that oil to get close to its smoke point the chemical properties of that oil change and turns it into a polymer which happens to be, yep, nonstick… similar to the coating on any nonstick pans or silicon baking ware.
A bit about temperature.
The smoke point of vegetable oil is about 400F or 200C which is what I’m using for my test. Visually, oil will form ripples over the bottom of a pan right before it starts to smoke so that’s an easy way to know when to stop applying heat. If the oil smokes a little bit it’s not the end of the world but but keep in mind that burned oil tastes rancid so let’s try not to do that.
Also, who wants to cook an egg at 400F? hopefully nobody. Traditional egg cooking temperatures range from say 140F to 160F and that’s way way below our polymerizing temperature but that’s not a problem. Once a polymer forms it stays there even if the temperature of the pan drops. Scrubbing and soap might remove it so don’t worry. If you want to retain that stainless steel original surface all it takes it’s some heavy scrubbing after every use. Something worth mentioning is that I used eggs cold from the fridge just in case you were asking.
Tonight I ran a 3 tests to help illustrate this whole thing and here they are:
Dropping egg onto cold pan and then cooking the egg:
As expected, this is the stuff of nightmares. I was pretty generous with the oil too (a common myth and the reason turn to nonstick)… but that won’t matter. The oil isn’t polymerized. The egg white is heavier than the oil so it will sink displacing the oil around it and making contact with the pan’s steel surface. Expect that egg to stick all over. I wish I had used a brand new pan to illustrate this better. I got some sticking going but not as much as I would have using a brand new pan. I still think you can get the idea from the following pics.
Heating pan to near smoke point temperature. Removing pan from stove. Cooking egg using the pan’s heat.
I coated the bottom of the pan with only a small amount of oil and discarded any excess completely. I only had enough oil to thinly coat the bottom. Heated the pan to smoke point temperature. I then removed the pan from the stove and dropped the egg in it. The pan’s heat did most of the cooking. Since the egg is cold from the fridge, that quickly lowers the searing hot temperature of the pan and the cooking actually had to be finished by returning the pan to the stove on low heat for about an extra minute. I got some browning around the white’s edge. Not a big deal.. The egg slipped right off the pan. Polymer success!
Pan reaching near smoke point temperature. Cooling pan to room temperature and dropping egg. Cooking egg over low heat:
This is my favourite approach because it allows me to cook the egg at a very low temperature which means having more control and avoiding any browning just like I would on a nonstick pan. I got a little bit of sticking though but only about 5 percent of what I’d get with the cold pan/oil test mentioned first. I’m sure I could do a better job at coating the pan and creating a really even polymer layer if I tried again.I still consider this a polymer success!
So what’s it gonna be? nonstick pans or polymerized steel?
Your choice but let me tell you, when you’re at your friend’s kitchen and there’s not a single nonstick pan in sight, it doesn’t have to be game over. You can still pull it off. I’ll have to say though, having cooked in many of my friend’s kitchen.. nonstick pans are the rule and not the exception which drives me crazy but that’s another story. Anyways, I still think this is a good thing to know. It’s not a trick. It’s a pretty common technique used my many cooks out there.
And that’s that!
The concept of polymerizing a skillet works on any kind of metallic skillet. Not just stainless steel and the process is exactly the same. Try it out if you haven’t and let me know how it goes!
