Lobscouse (Sailor's Stew) - Skipper labskovs

Brown meat and cook onions in the butter, stirring occasionally. Add stock, beer, bay leaves, salt and pepper. Cover and simmer for 20 minutes. Add potatoes and continue to simmer for 2 hours. Mash any remaining pieces of potato, so that you have a thick 'gravy' with just a few pieces of potato. Serve in bowl with 1 tablespoon butter on top. Sprinkle with onion tops.
