  3. Add the butter, let it melt, mix in the flour and let it cook for 2-4 minutes.
  4. Add the stout and deglaze the pan.
  5. Add the broth, Worcestershire sauce, grainy mustard, bay leaves, salt and pepper, bring to a boil, reduce the heat and simmer for 30 minutes.Ladle the soup into oven-proof bowls on a baking sheet, top with the sliced bread and cheese and broil until cheese melts, about 1-3 minutes.
