Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>First, make the shortcrust pastry. In a large bowl, rub the cold cubed butter into the flour using your fingertips until the mixture resembles fine breadcrumbs. Working with cold ingredients and minimal handling prevents the butter from melting, which is crucial for achieving a flaky, tender pastry.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Stir in the icing sugar and salt, then add the beaten egg and just enough ice-cold water to bring the dough together – it should be soft but not sticky. Form into a disc, wrap in plastic wrap, and chill for at least 30 minutes. This resting period 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 180°C (160°C fan/350°F). On a lightly floured surface, roll out two-thirds of the pastry to about 3mm thickness and use it to line your tart tin, leaving a slight overhang. Prick the base with a fork, line with parchment paper, and fill with baking beans. Blind bake for 15 minutes, then remove the beans and paper and bake for another 5 minutes until the base is pale golden and set.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>While the base is cooling slightly, roll out the remaining pastry and cut into 1cm strips for the lattice top. For the filling, gently warm the golden syrup in a saucepan until it becomes more fluid – don't let it boil as this will make the final tart too hard. The warming process makes the syrup easier to work with and helps it combine evenly with other ingredients.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Remove the syrup from heat and stir in the breadcrumbs, lemon zest, and juice. The breadcrumbs are crucial as they absorb some of the liquid, creating the perfect set texture while preventing the filling from becoming too runny or too firm. The lemon cuts through the sweetness beautifully.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Pour the warm filling into the part-baked tart case, spreading it evenly. Arrange the pastry strips in a lattice pattern over the top, trimming any excess pastry from the edges and crimping to seal. Brush the lattice with beaten egg for a professional, glossy finish.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Bake for 25-30 minutes until the pastry is golden brown and the filling has set but still has a slight wobble in the center – it will continue to set as it cools. If the edges are browning too quickly, cover them loosely with foil.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Allow the tart to cool in the tin for at least 30 minutes before carefully removing. The filling needs time to stabilize – if cut too soon, it may ooze. Serve warm or at room temperature with a dollop of clotted cream or vanilla ice cream. Your treacle tart will keep well in an airtight container for up to 3 days.</li></ol>
