Begin by adding the onion, garlic and carrots to a large casserole pot with a glug of oil and allow to cook over a medium to low heat until the onions soften. After around 5 minutes remove from the pan and set to one side. Using the same casserole dish add another glug of oil and allow to heat. Take the roughly chopped Seitan and toss on flour and seasoning then place in the casserole dish and stir once the pieces start to brown. Once all Seitan has been browned on both sides add back in the onion, garlic and carrots. Pour in the can of Guinness which will help to remove any flour that has stuck to the bottom of the pan. Increase the heat then once boiling add in the red wine or port, dark soy sauce, marmite, bay leaves and stock. Allow to cook for 15-20 minutes on a medium heat then have a taste and adjust seasoning if necessary. For more salt add in extra dark soy sauce and for more heat add in extra white pepper and freshly ground black pepper. Next add in the fresh rosemary and oregano followed by the pearl barley, stirring every few minutes so it doesn’t stick to the bottom of your pan. Keep an eye on liquid too as your may need to add another half a pint of vegetable stock or red wine depending on how rich you like your stew to be. Allow to cook for a further 10-15 minutes or until the barley is soft when eaten.
For the dumplings simply rub the butter into the flour using your fingertips until you have a fine crumble like texture. Add in the cheese, herbs, horseradish and seasoning then combine well before finally adding in a splash of water. Add in another if you need to, enough to bring the mixture together like a dough. Next roll into rough balls the size of a cherry tomato or a little larger and place on top of the stew. Cover with a lid and cook over a medium heat for 12-15 minutes. Note – Ensure you have enough stock/gravy in your stew so that the barley doesn’t stick while you cook your dumplings.
Serve with a big bowl of steamed buttered greens or shredded cabbage with a generous sprinkle of white pepper.
