Pictured is a dutch oven very similar to mine that I use for frying. It's my deep fryer and used for nothing else. I use it on the stove and on a propane burner outdoors. If you do a lot of deep frying like chicken, fish, shrimp or anything else in larger amounts you really need to get one. If you would like information on how to season it properly PM me.
This is the same process I will refer to for deep frying anything. Chicken tenders, chicken, breaded steak, breaded pork loin, shrimp, fish and anything else you would like to deep fry.
Always when frying use the method of when it floats it's done. This holds true for most anything you fry.
