Giant cast iron skillet!
I have never met your grandmother, but I feel confident in saying that she would think this is way too much skillet. Think about frying a couple of eggs in this sucker – how would you ever get two pats of butter to distribute evenly across the surface of this nonsense? You’d have to use a disproportionate amount of fat in order to prevent the eggs from sticking. Ditto for potatoes or crepes or whatever. This is more skillet than is needed for most tasks. We call shenanigans on this skillet!
