Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Start with the pastry base. In a large bowl, combine the flour and salt. Add the cold cubed butter and rub into the flour using your fingertips until the mixture resembles breadcrumbs. Cold butter is crucial as it creates steam when baking, resulting in flaky layers.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Gradually add the ice-cold water, a tablespoon at a time, and mix with a knife until the dough just comes together – it should be firm but not sticky. Shape into a disc, wrap in cling film and refrigerate for at least 30 minutes. Chilling allows the gluten to relax and prevents shrinkage during baking.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Preheat your oven to 200°C (180°C fan/400°F/Gas 6). Roll out the chilled pastry on a lightly floured surface to about 3-4mm thickness, making it large enough to line your pie dish with a slight overhang.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Carefully transfer the pastry to your pie dish, pressing it gently into the corners without stretching. Trim the excess leaving a small overhang to allow for shrinkage. Prick the base several times with a fork to prevent air bubbles forming.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Line the pastry with baking parchment and fill with baking beans or dried rice. Blind bake for 15 minutes, then remove the paper and beans and bake for another 5-7 minutes until the base is lightly golden. This pre-cooking ensures the pastry remains crisp when the filling is added.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>While the pastry is baking, prepare your filling. Heat a tablespoon of oil in a large frying pan over medium heat. Add the onions, carrots, and celery, cooking gently for 10 minutes until softened but not browned. Add the garlic and cook for another minute until fragrant.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Increase the heat and add the minced lamb. Break it up with a wooden spoon and cook until browned all over, about 5-7 minutes. Sprinkle over the tablespoon of flour and stir well to coat the meat.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Stir in the tomato purée, Worcestershire sauce, herbs, red wine, and beef stock. Season generously with salt and pepper. Bring to a simmer, then reduce the heat and cook gently for 20-25 minutes until the sauce has thickened and reduced. The mixture should be moist but not watery – a thick consistency will prevent the pastry from becoming soggy.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Meanwhile, boil the potatoes in salted water until tender, about 15-20 minutes. Drain thoroughly and return to the hot pan for a minute to dry out – this helps achieve fluffier mash. Mash well, then beat in the butter and warm milk until smooth and creamy. If using, stir in the egg yolk for richness. Season to taste with salt and pepper.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Spoon the lamb filling into the pre-baked pastry case, spreading it evenly. Carefully top with the mashed potatoes, starting from the edges to create a seal (this prevents the filling from bubbling up and over). Use a fork to create a textured pattern on top – these ridges will crisp up beautifully during baking.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>If using, sprinkle the grated cheese over the potato topping. Place the pie on a baking tray (to catch any overflow) and bake in the preheated oven for 25-30 minutes until the top is golden brown and crispy, and the filling is bubbling hot.</li><li class="MethodStepper"><h4 class="step-title">Step 12</h4>Remove from the oven and allow to rest for 10-15 minutes before serving – this resting time is important as it allows the filling to set slightly, making it easier to portion. Serve with seasonal green vegetables for a complete meal. The pie will have a wonderful contrast of textures: crisp pastry base, rich savory filling, and fluffy potato topping.</li></ol>
