TO MAKE IN A SLOW COOKER . . .
Toss the braising steak in the seasoned flour. Heat a little oil in a large non-stick frying pan and fry the beef in batches until it has a good colour on all sides. Transfer to the slow cooker when browned. Add the Guinness to the pan and let it bubble up. Scrape any caramelised bits off the bottom of the pan then pour the whole lot on top of the beef.
Add the rest of the ingredients EXCEPT the beef stock (you won’t need it as this will make the finished dish too liquid).
Give everything a stir then cook on low for 6 hours until the meat is tender.
