Free-Form Apple Pie

Step 1: To make the pastry, beat butter, sugar and extract in the bowl of an electric mixer until light and fluffy and add egg and beat until combined.

Step 2: Sift the flours and custard powder together, then gradually add to the butter mixture, beating until combined and then transfer dough to a lightly floured bench, shape into a flat disc and enclose in plastic wrap and refrigerate for about 1 hour, or until firm.

Step 3: Roll out the pastry between two sheets of baking paper to form a 30cm circle and then lift paper onto an oven tray, remove and discard the top layer of paper.

Step 4: Peel and core apples and cut into quarters, then cut into 1cm-thick slices and place in a bowl with the custard powder, sugar and lemon juice, and toss to combine.

Step 5: Spoon mixture into the centre of the pastry, leaving about a 5cm border and using the baking paper as a guide, fold pastry over apple mixture.
