This soup originates from the East Coast of Scotland. Skink is Gaelic for "essence" but it is now more commonly means "soup-stew. This is a simple and quick version of cullen skink, traditionally it should be prepared with Finnan (whole smoked haddock), I have also included a few mussels to finish the dish but of course these are optional.
