I dont currently own a deep fryer apparatus of any sort. Ive been frying on the stove in a big cast iron. Looking to add something to the arsenal and not sure what would be best. Outdoor cooking is something I enjoy - have a smoker, grill, and a griddle that get used once a week or so. I have a tendency to go big or go home and am considering a propane something - cajun fryer or something along those lines to keep the mess out of the house. Would that be worthwhile for a family of 4? Or is it overkill? I would keep it on a covered patio - any issues with leaving the oil in it? I see guys talking about filtering the oil, hows that work?
