Gobbiners Cafe in Ossy make loose potato pie for their outside catering. It consists of potatoes, steak, onions and carrots with a pastry on the top.
Scouse was, but will have changed a bit now, all the leftovers bunged in big pan and left to "gain flavour". It was stirred around bringing the bottom to the top, and continually added to. The scouse pan was rarely empty, being topped up every day.
