I’m going to ramble a bit here, too many seed oils are processed to death with many chemicals being used and when you heat them to frying temps they become toxic, and if you use them more than once it becomes even worse.
Olive oil is processed by squeezing the oil out in presses, Olive oil is about as natural as you can get if the olive trees are not doused with chemicals.
lard, I grew up with everything being fried in lard, used in baking, etc.
The best fried chicken ever is done in lard after you fry a sliced onion in it to flavor the oil.
However, there are so many growth promoters and antibiotics used in hog feed anymore that I cant help but believe that lard is nothing more than toxic waste oil when heated these days as heat changes the toxicity of those unnatural things used to make a pig grow faster than normal.
Those growth promoters, antibiotics, and diseases are trapped in a hogs fat, they are a scavenger after all.
I use a lot of olive oil, dont bother with the cheap stuff as it is blended with corn oil,soy oil,etc.
I fry a lot of fish in olive oil and I do not use a lot, just enough to cover a filet in a cast iron skillet, heat recovery time is key here and I fry at 375 and never once smoked the olive oil.
Buy it in the large bottle, that will save you some money and there are countless uses for olive oil if you are worried about it spoiling, salad dressings from scratch, in place of butter, marinades on and on and its good for you.
If you are unsure how an oil is processed google it, some things will about make you sick reading up on it.
I agree with you on peanut oil, gives me a headache and tears my guts out.
