The green parsley sauce ladled over the top, called 'liquor,' traditionally started life as the leftover cooking water from stewed eels.
A hand-raised pie of minced beef in shortcrust pastry is served alongside mashed potato and doused in a bright green parsley-flecked liquor sauce. Family-run shops, some open since the early 1900s, serve it at simple tiled counters with communal tables.
