I'd call it "tater 'ash" - short for Potato hash. Simply made from chopped stewing beef, onions and carrots, boiled up together for a while. A staple of the Northern working class cuisine for decades Another sign of the trouble restaurants are in when they have to continually seek out dishes with cheap ingredients. Their overheads, which are largely outside their control, are rising steeply.
I wouldn't class it as a romantic meal out though - more a working class dinner .
Those are the origimals (still made in Eccles I think). There is a video somewhere. The secret is Vostizza currants, and rolling the pastry into many layers
Here's the video I had in mind -there are many others, but this is the real thing . Eccles Cakes
