Next add half the meat and cook until nicely browned all over. Repeat the process with 1 tbsp of the vegetable oil and diced chuck steak.
Sprinkle on the flour and stir in well, let the flour catch slightly, this helps to give the sauce a nice colour.
Then add the tomato puree, stock cube, Worcester sauce, water, thyme and sugar.
Heat the other 2 tbsp oil in a frying pan and add the onion, carrot and garlic and cook gently until softened and golden brown.
Tip the onion mixture into the casserole dish with the beef and stir together.
Season well with salt and pepper and bring to a gentle simmer, cover with a tight fitting lid.

After 1/2 hours make the dumplings, by placing the flour, salt, suet, parsley, horseradish and egg into a bowl.

Break off 8 small pieces and roll them into small balls.
Place them on top of the stew.
Return the pan oven uncovered and cook for a further 35-45 minutes, or until the dumplings are nicely browned and crunchy.
