This Is What Happens When You Deep Fry a Frozen Turkey 164
Too late for many east-coast Americans, but perhaps in time to stop a blaze or two in California, an anonymous reader writes with this video of "a controlled demonstration of why it is a bad idea to fry a frozen turkey." My brother this morning assembled (despite poor directions and questionable parts fit) a deep fryer for a Thanksgiving turkey; we're optimistic, and the turkey seems to be fully thawed at least.

Every video of the turkey being put in results in an overflow of displaced oil which catches fire.
The water will 'boil' due the very high oil temp.. but most of these videos seem to fail at 'use the proper amount of oil'.

This is nothing special. If you can get a decent quantity of water under a pan of ignited oil (just pouring it on top works - remember water denser than oil) then you can get a pretty good fireball. I've seen it done with a few tens of grams of oil and a decent water-pistol - that was enough (in the sort of "don't do this at home kids" sort of sense of enough).
What I'm really curious about is whether this would happen with a normal dry cleaned turkey straightforwardly frozen or if it's extra water added

Obviously you don't do much cooking. Frozen products are often covered with a layer of ice from a couple of sources. Major source, warm bird as it is getting frozen, the freezer is a very dry environment drawing moisture from inside the warm meat to the surface where it freezes. Next the movement from the freezer to the fryer takes time and frozen meat will condense moisture from the atmosphere and freeze on it's surface. So upon first insertion you have free water to react with the oil. Specifically water

That's kind of what I was thinking. Why would a frozen turkey contain any more water than a thawed turkey. I had no idea that they put extra water in the frozen ones to jack up the price. Of course, we only buy fresh, (never frozen) turkeys for thanksgiving, and for almost all our meat.
Okay, so I got curious after this. Given that we are talking about thanksgiving turkeys, so the US, I found the USDA explanation [usda.gov]. Summary. No actual water injection. Apparently no glazing like seafood [seafish.org]. However 12% or so "retained water" or "absorbed water" should be declared on the label and things like "up to 10% of a Solution" may be used to help with flavour. The poultry its self likely has more than 65% water, but I guess that is normally more bound up with the meat, since it doesn't cause a prob

A traditionally immersion-chilled carcass absorbs a good deal of water; immediately freezing that carcass traps more water in the tissues.

The problem isn't the right volume of oil to submerge the bird, they had that right in the video as you don't see oil slopping over the side of the pot as the bird goes in. What happens is the hot oil melts and boils the ice around the bird and the steam explosion throws the oil over the edge of the pot.
Now, a very tall pot, say 2m, might contain that oil.

But the flying hot oil can still blind, permanently disfigure and maim people.
My guess is chunks of ice can end up creating bigger expanding bubbles of steam than water for the same amount of water, since the ice = more water stuck together. And bigger expanding bubbles = more flying oil. But either way too much water in oil is not a good idea.

It will happen if you adiabatically increase the atmospheric pressure around the pot at a compression ratio over 14:1 [wikipedia.org] or you use fuels [wikipedia.org] to deep fry the bird or just slowly raise the temperature of the pot to the point of it glowing-red

Ice isn't more water stuck together. Ice actually has a lower specific gravity than water (ice floats).
I think the biggest problem is that the heat of fusion (the amount of heat needed to melt the ice) actually gives it an opportunity to melt and then boil a bit slower. And that gives the ice more time to sink below the oil. Once it melts and then boils (at the bottom of the pot) it displaces a larger column of oil above it.

Deep frying a whole turkey makes it come out extremely juicy -- it doesn't have that "fried" flavor or taste. Cooking in the oven gets you a bit dryer turkey. What happens is the hot oil sears the skin, trapping the juices inside. Usually you inject them with a butter based solution, seasoned with various spices, and that gets embedded into the turkey meat. Oh, and when you inject the bird, first figure out which way you are going to position it in the pot, and make sure the injection holes are at the top (try to reuse the same injection site, and with different angles / depths), so that the juice doesn't run out into the oil when cooking.
And yes, the first time I had seen this done was in Arkansas. But like I said above, it doesn't come out greasy or anything like that.
