Why can't you retrofit fire suppressing foam in the kitchen, like one does in a commercial kitchen range hood? I've seen this done on kitchen remodels. There are residential range hoods (Viking, Wolf, ...) which have a wall-mounted button or a pull which 1) kills the fuel source and 2) smothers the range area with fire suppression (class BC or K) to put out the fire and prevent re-ignition. Totally ruins your food AND needs to be cleaned off promptly since it's corrosive.

Kitchens are by far the most likely source of domestic fires.
