Hey all,

A couple years ago, I bought a fry daddy. I used it a time or two for parties and such, but then I put the lid on it and sealed it up. Now, the lid is for sealing the baby up to store the oil in it right? And you just leave the oil in and reuse, topping it off when needed. The more you use the oil, the more "Seasoned" it becomes. --That's the way the instructions put it, and it's the way I've always understood it to be.

Well, tonight was literally the first time I've used the thing in a couple years. I took it out of the cabinet, and pulled the top off. The top was kinda varnished on with some darkish-looking oily residue. --ANd the oil reeked. It smelled just like linseed oil, which is NOT a cooking oil. It's the oil you use to oil paint. Any artists here know what I'm talking about. It has a turpentine-ish smell. Anyway, I thought that was kinda odd, but I figured it was still ok. Well, I plugged it in, let it warm up, and I noticed it started to boil much more quickly than normal. When I put the food in, the excitement began! First of all, it started foaming. FOAMING. Cooking oil doesn't foam. It bubbles when it boils, but doesn't foam. Also, the smell the stuff was putting off once it started foaming was VERY noxious. It smelled very strongly of some kind of heating oil...had a very solvent-like twinge to it. --And then the foam just went CRAZY. I unplugged it, and it still foamed WAY OVER the top of the pot. --And, as per the instructions, it was only filled to about 1/3 of the way. VERY odd. So, I poured all the old oil out, cleaned up the HUGE mess in my kitchen, and thoroughly washed the thing out. WHen I refilled it with fresh oil, it acted perfectly fine, and the food was great. The smell was great, no foam, nothing. So, WTF?
Can cooking oil "degrade" over time to a toxic substance? Of course, the things I described don't NECESSARILY mean the oil was toxic, but I can guarantee, the food would have tasted like it was basted in carburetor cleaner had I eaten it. --And what is with the strange reactions and the varnish-looking oil on the lid? I know gasoline changes when it sits for a while. It creates a varnish. It's very hard and gummy. Can cooking oil do this also? Either it's possible or my oil was replaced by some evil person looking to kill me next time I try to fry food. What are your thoughts?

Simple as that? You're sure? I'm really asking, because obviously I don't know. I've never heard of or seen rancid cooking oil before. So, what are the characteristics of rancid oil? Is it very dangerous? Toxic even?

Well, no need to worry about that. It's probably a mile away by now. Down the drain it went, followed by much water.

I thought this was going to be some weird, sexual, coming out of the closet band camp experience thread.

Holy Cow....... 2 years :Q

That oil not only turned rancid but it probably became a lifeform of it's own ;)

The more you use the oil, the more &quot;Seasoned&quot; it becomes

What a load of bologna. I get about two uses out of my cooking oil before I have to trash it and start fresh. Don't keep topping off the old. The fresher your oil, the less your food will taste like the last thing you cooked in it. I'm not sure if they sell it in grocery stores or not but look for hydrogenated vegetable oil in solid blocks instead of in bottles. It's cheaper that way.

So, what are the characteristics of rancid oil?

See very first post.

Down the drain it went, followed by much water.

Down into the city sewer or down into you septic tank? Either way, that's a no-no. You should have found a container to throw it away in. You're just causing yourself further problems by coating your drain pipes with that stuff.

Got any more cooking questions?

I cook my fries in Castrol Synthetic 10W30. I get 10,000 miles out of a oil change, fights the gummy deposits on the lid, and prevents high speed breakdown.

:p

Cooking oil (and any other oil) decomposes at high temperature. It also decomposes in time, even if it is not used at all (basically it reacts with oxygen from air). The by-products can be toxic and/or cancerogenous. Do not reuse the oil more then once or twice.

&quot;The more you use the oil, the more &quot;Seasoned&quot; it becomes&quot; - that's a malicious marketing trick. Tried finding any small print in the instructions :)

&quot;cancerogenous&quot;? Hehe, I think that's better than the real word.

It's okay to use cooking oil more than TWICE, geez. My limit is basically when it becomes noticeably darker or I've cooked a lot of stuff, kind of a subjective thing. I think a month though would be the limit, even if you used it only a few times.

&quot;Partially hydrogenated vegetable oil&quot; basically is cooked oil, it hydrogenates during the heating, each time doing it more and more. Hydrogenation is actually bad for you.

Of course, I need to go change the oil in our fryer. Before I went on vacation, I cooked bacon in it, and I think the bacon grease is probably rancid by now, even if the vegetable oil is okay.

True, but my personal tolerance for &quot;tasty&quot; oil is pretty low.

Partially hydrogenated vegetable oil basically is cooked oil, it hydrogenates during the heating, each time doing it more and more.

Questionable, that means that after each time you used the oil it would get harder until it was a solid at room temperature. My experience doesn't find that to be true.

Hydrogenation is actually bad for you.

True, but cheaper. :p I really don't like fried foods that much anyway.
