Here. This one is for all those who either went to Cook and Baker's School in the Army, or at least pulled enough Kitchen Police duty (KP) to have had some work helping the cook fry stuff. Or maybe, like me, you worked the French Fryer in Mickey Dees in your yute.
The scene seems to suggest that this cook is enough of an expert to have been assigned (or maybe he assigned himself) to make an instructional video on cooking some version of potstickers. That would be the fried version, not the steamed version.
There's a simple rule for deep-fat frying, and that rule is to have the right proportion of oil to fryable food so the food has enough cool (heat sink capability) in it that the frying process can be controlled, because the vid shows what happens when the cook ignores that proportion and heats far too much oil. The food flashes into steam below the surface of the oil, causing an explosion which throws hot oil at 400 degrees or so all over the place. That hot oil can get into the fire and create a massive Boiling Liquid Explosive Vapor Explosion (BLEVE), which can approach high-order explosive status. Even if it doesn't blow the kitchen off the map, it will surely injure the personnel. Okay, it's not a true BLEVE because it isn't contained by a vessel (tank), but it's close enough and the results could be the same: huge fireball.
In this vid, the cook remembered one of his emergency procedures: shut off the cooking flame, then he put the big pan on the floor, also a good reaction, but then he forgot to cover the pan. Instead, he tried to save the food! After getting close to several of the explosions of hot oil, he was reduced to a cowering, blubbering idiot who could do nothing but watch more explosions.
Most of the commenters over at the hard-bitten milblog Castle Argghhh! yukked at this, but it is exactly the same problem that probably just burned down at least a dozen houses across the country, when deep-fat turkey-fryers were improperly used.
