Pine nut dulce de leche tart

1.For sweet pastry, process flour, icing sugar and butter in a food processor until it resembles fine crumbs. Add egg and pulse until it forms a ball, adding a little iced water if necessary. Shape dough into a ball, wrap in plastic wrap and refrigerate to rest (20 minutes).

2.Preheat oven to 180C. Spread pine nuts on an oven tray and roast, stirring occasionally, until golden (8-10 minutes). Set aside.

3.Roll out pastry on a lightly floured surface to a thickness of 5mm and line a 24cm-diameter tart tin sprayed with cooking oil spray, pressing pastry into the tin well. Trim edges, wrap with plastic wrap and freeze (30 minutes to 1 hour).

4.Line pastry shell with baking paper and blind bake until just cooked, turning every 10 minutes to cook and colour evenly (25-30 minutes). Remove from oven and remove paper and weights. Reduce temperature to 150C.

5.Combine condensed milk with 1 tsp sea salt in a bowl. Spread roasted pine nuts evenly in pastry shell, then pour in condensed milk and bake, turning occasionally, until golden and set (45-55 minutes). Cool for 15-20 minutes before serving.
