Step 1

Roll out the pastry on a lightly floured surface until big enough to line a 23cm fluted tart case, about 3cm deep. Line the tin with the pastry and fold the overhang over the sides. Chill for 30 mins.

Step 2

Heat oven to 200C/180C fan/gas Line the tart with greaseproof paper and baking beans. Bake blind for 20 mins. Remove the beans and paper and bake for 10 mins more until the pastry is pale golden and sandy.

Step 3

Meanwhile, mix the golden syrup, breadcrumbs, lemon zest and juice, ground ginger and eggs together. Once the pastry is ready, lower the oven to 160C/140C fan/gas Using a small serrated knife, carefully trim the edges, then tip in the treacle mixture and bake for 55 mins-1 hr until the filling is golden and crisp, and feels set to the touch.

Step 4

When the tart comes out of the oven, arrange the ginger slices over the top. Drizzle with some syrup from the ginger jar, then lift from the tin to a serving plate and serve warm with vanilla ice cream or custard.
