Yup. Chefs rarely use nonstick cookware outside of baking or specifically making omelettes. For the majority of their uses, it's either stainless, cast iron, or enameled cast iron. Non-stick got its foothold when the feds went on their "fat is bad for you" kick. They took all the fat out and added sugar to products to fix the texture. Proteins stick to steel when the steel isn't sufficiently hot before food is placed…

> Chefs rarely use nonstick cookware outside of baking or specifically making omelette. Citation needed? It sounds implausible to me that a majority of professional cooks seek to make their own job harder when they've got seven other dishes to make by tending a nonnonstick pan.

As a college student with no idea what I was doing, I tried to stir-fry everything at maximum heat and would quickly burn food to a regular pan.

After I learned to be a halfway competent cook, I discovered most cooking methods don't stick at all! Caramelizing, braising, roux, simmering, on and on- mankind learned to cook with ordinary cookware, and all the classic recipes and techniques reflect it.

It's not a matter of being a great cook - you simply don't need nonstick to braise or simmer, for example. So I'd phrase the exercise of learning to cook with steel pans as simply "learning to cook".

I do not trust BPA-free plastics either. I have switched from cans to tetrapaks where possible. My confusion came from some misleading industry documents I read which suggested that PFOA/PFOS/C8 had been replaced with a process that did not require fluorosurfactants. I feel like the information about these chemicals is so confusing, it's hard for a non-chemist like me to understand.

Can you elaborate ? What's wrong with cans ? If they're aren't just aliminum what are they coated with on the inside ? How would tetrapak fare better ?

One thing I've noticed with stainless steel is that if you have hard water, you get some calcium buildup and things stick like crazy. Anytime my stainless steel pans start having problems I soak a bit of vinegar on them for a bit, scrub them, then they are good again. However my preference is typically cast iron. A good seasoned coating (and a couple decades of use that results in a polished surface) is typically muc…

> if you have hard water, you get some calcium buildup and things stick like crazy. Anyone using stainless cookware should be using Bar Keepers Friend, it's like magic on stainless steel. The oxalic acid in it removes calcium buildup and helps passivate the stainless steel, the surfactant in it somehow dissolves browned oil stains (even the nasty burned in ones on the bottom of the pot) and the feldspar dust in it pr…

+1 for Bar Keeper's Friend. It really is the best.

For folks having issues with food sticking to cast iron or carbon steel, try learning to cook on stainless. It's much more prone to sticking, but if you can get the technique down well enough to not have eggs stick on stainless then switch to cast it's a walk in the park.

Tomatoes+Onions+Eggs, anything watery or sour = stainless with some drops of olive oil

Meat, Potatoes = cast iron with sunflower oil

anything else (crepes, pan cakes) = carbon steel with either canola or sunflower oil

To prevent eggs to stick putting some onion rings or slices of ginger helps.

The most difficult is to get good non-oily crepes.

Humanity probably needs plastics, I can’t see how we go back. Also, it’s interesting to consider whether >50% sugar induced obesity rates are having a larger effect on quality of life…

perhaps ironically, it may be the chemicals in our environment and not dietary choices which are driving high obesity rates: https://slimemoldtimemold.com/2021/07/07/a-chemical-hunger-p...

It’s no surprise that extreme excess of food due to low cost results in massive obesity.

This is replicated in essentially every mammal study where one provides an unlimited amount of food and comfort to an environment.

If sugar were taxed 1000% percent we would see a massive change in global health.

Learning to "proof" steel is something worth spending time on. I was taught by a Chinese room-mate at college who showed me how to prepare a wok. - 1. Heat the thing up as HIGH as it will go, till parts of the base glow red if you can. Gas is better than electric heat. - 2. splash a little vegetable oil in and swill it around to cover all the surface. It may ignite, ignore the short lived flames, but brush it around…

Heating edible oils to very high heats does tend to produce harmful chemicals as well. EDIT: For example: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4029104/

Right, but unlike fluorinated compounds those toxins can be broken down by your body and flushed out (I could be wrong?). For example, alcohol is pretty toxic to us.

It does not look cool but vapor cooking is a miracle. It is fast, it is clean, it preserves nutriments. People who like to "cook" don't like it because they can't perform their magic rituals. Cooking has always seemed something very religious to me... Cooking some stuff for a long time, adding secret ingredients supposedly to give "extra" taste... Putting stuff on the pan, then turning on the oven jsut to melt a layer of cheese.. Seems to be so much work, so little efficient. Most of my cooking talents consist in adding salt and pepper, spices, olive oils, seeds, lemon juice to good produce with delicious bread. You can taste the things you are eating, it takes less time and it's healthier. It's even healthier for your indoor air. Come to the bright side.

"The chemicals are turing the plebs fat!" -- Seriously, While travelling SE Asia, every single rice field from Myanmar, Thailand, Malaysia, Philippines, Indonesia, Japan.... etc. It was REALLY common to see the petro-chem signs in the fields advertising the petro-chemical compound's name brands. (I couldnt read local languages and the 'English' name brands were not what we have here, so they didnt form a stark imprin…

Hopefully high purity water becomes more available as the technology gets deployed to these areas.

The study didn’t actually find anything related to cookware. Modern Teflon in the US doesn’t expose people to PFOA/PFOS like old version did due to new regulations. The chemicals could also be entering peoples body’s through drinking water or bioaccumulation in meat or plants. You should throw away nonstick cookware from before 2013, but new nonstick cookware sold in the US does not have PFOA. I believe the EU follow…

The risk from burning a Teflon pan is enough reason to avoid it. I first heard about this from a person who kept rescued birds. Apparently birds are especially susceptible to toxic fumes. People overheat pans all the time. It seems crazy to not take that failure mode into account in evaluating Teflon's safety. I also do not FW fluorinated ski wax.

I personally use a temperature-control induction stovetop to make sure it can never overheat.
