I made this last night on a whim.
Seasoned cube steaks w/ salt & pepper and went dry-wet-dry in a seasoned flour and milk/egg bath. Pan fried 2 min/side in cast iron w/ 50/50 olive oil & butter. Oil may have been a bit deep. They weren't really crispy, but the coating stuck. Thinking about it, maybe they aren't supposed to be crispy? Dunno.
Made a pan gravy w/ roux of leftover fat and flour and whisked in milk then seasoned w/ black pepper and salt. Gravy was a little heavy on flour and much better after I discarded half and added more milk.
Kids loved it and I thought it was pretty good. Could definitely improve upon the technique. Next time will use bigger pan and more steaks. I did it in batches and put them on a wire rack in the oven to keep warm.
Not sure what exact cut I used. They were labeled as 'cubed steaks' and that should typically be bottom round cut thin and run thru the cuber. They were plenty tender and only had one bite that was inedible gristle.
