In my training to be certified, we had to learn about cooking in oil although we never used it is the cafeteria I worked at but I learned a LOT of important stuff about grease that I did not know.

It is a tricky thing if you do not know for SURE what you are doing but perfectly safe if you educate yourself on it. We have a deep fryer on the boat that I use a lot and I preach at the guys that NO ONE is to use it except for ME! Just like king2005 that started this thread, you have seen it done 100 times so you are sure you know how to do it.... seeing it done and KNOWING how it is done two different things... so I forbid them to use that deep fryer. The end result of one deckhand that only thinks he knows what he is doing could kill us all. It is the young one that scare me the most, they are the ones that know everything but only enough to get someone hurt.

My advice is if you have never had proper instructions on deep frying, DON'T TRY it... it could kill you.
