I you want the best flavorful and most unhealthy oil, try using lard. The only time I use it is when deep frying a turkey.

HHHmmm.   The father in law just had a hog killed that was really fat.  With Christmas coming out, instead of my saved up peanut oil, I may have to try the lard option.

Well we gave it a go, and followed some of the great advice here and.... and...

It was GREAT!!  We had some of the best french fries ever!  Keri fried them in peanut oil and then tossed them in truffle oil.  Holy Cow!!  They were awesome!!

Thanks everyone for all your help!

I like foods fried in peanut oil but I've never cooked with it.

I'm jealous. A deep fryer would make frying a cooler full of crappie or white perch a whole lot easier.

How did she use the truffle oil with the fries?

You drizzle it on afterwards.  Even better if you have some fresh truffle to shave on but that's some Steez-level $$$.

Back to the topic at had, peanut or canola is probably the best combination of high smoke point and price. Safflower has a high smoke point and almost no taste, but it's a little expensive.

Another tip, if you strain the oil through a coffee filter laced in a strainer, it'll last a long long time. It works best when the oil is just a little warm.

Last thing, if it's getting near the end of the oil's life (or you just want to)   I fry a couple of bacon strips in the oil (careful not to burn them) and then fry your fish, potatoes, and hush puppies.   

I did a quick search on the oil, what's the difference between white and black?  Thanks.

The black is a little more earthy, the white a little more fragrant...Honestly, not a huge amount of difference.

Thanks VolFan 

Make sure to try some deep fried Twinkies. I kid you not.

That's the only reason I bought a fryer! I warn you though once you start frying your own fish, store bought and/or restaurant fish Fry's will be a thing of the past.
