Glad you're all OK.
I gave up frying anything that needs more than a few tablespoons of oil on the stove years ago... saw too many of those grease fire videos the fire safety folk put out.
My 15-year old fry daddy is my go-to tool for anything that needs frying. I've even completed repurposed my turkey frying rig to beer-only use and bought one of those butterball/masterbuilt electric fryers for turkey and other "bulk frying" events (can only do up to a 14 lb turkry, but that's plenty for up to 8 adults).
I'm a big fan of keeping fire extinguisehers nearby, and checking their serviceability too -both at home and in your vehicle. I've had 2 occasions where I've used/almost used extinguishers with vehicles.
Once was with my own car smoking like crazy, but it turned out to be a poorly-installed oil filter that sprayed oil all over the engine, so no fire, and no extinguisher needed, but I was ready.
The other time was in a HMMWV that had an electrical fire. The extinguisher that was mounted in the vehicle (and showed "green" on its gauge and was recently inpsected) gave a 1 second burst of spray when it was used (esssentially failed). I ran into a nearby, locked building (for which I fortuneately had a key) and got another extinguisher, tossed it to my driver (who was still dumbfounded by the failure of the first extinguisher) and he was able to deal with the fire. It's good fortune it happened when we did, becuase we were parked on a concrete slab at the time, having temporarily come in from an exercise where we'd normally be parked on grass/leave/etc and may not have had an alternate extinguisher near by. Bottom line: Get and extinguisher and get a backup!
