METHOD
Prepare the Mince Filling:
- In a large oven-proof casserole dish, heat a splash of oil over high heat and add the mince. Cook until browned, allowing the fat to render out.
- Add the chopped onion, carrots, and celery. Cook until softened, about 10 minutes.
- Add the garlic and mushrooms to the dish, cooking for another 5 minutes until the mushrooms release their moisture.
- Stir in the tomato purée and Worcestershire sauce, cooking for 2-3 minutes.
- Pour in the beef stock, add the fresh thyme and bay leaf, and season with salt and pepper to taste. Bring the mixture to a simmer, then reduce the heat and let it cook gently for about 30 minutes, uncovered, to allow the flavours to meld and the sauce to thicken.
Prepare the Dumplings:
- In a mixing bowl, combine the self-raising flour, suet (or butter), baking powder, chopped herbs, and a pinch of salt.
- Gradually add the cold water, mixing with a fork until the mixture comes together into a soft dough.
- Divide the dough into small balls, about the size of a golf ball.
Assemble the Pie:
- Preheat your oven to 180°C (160°C fan, Gas Mark 4).
- Once the mince mixture has thickened to your liking, arrange the dumplings on top of the mince in the casserole dish.
- Place the dish in the preheated oven and bake for 25-30 minutes, or until the dumplings are golden brown and cooked through.
