Add flour, butter, sugar and salt into and mix 6 seconds / speed 6
Add egg, water and ACV and knead 25 to 30 seconds until the dough starts to clump together
Remove dough onto a very lightly floured bench or silicon mat, and with floured hands lightly press the pastry together into an oblong shape (you will roll it out as an oblong shape so it helps to prepare this shape before resting in the fridge)
Wrap in Gladwrap and refrigerate 30 minutes
Roll pastry out on a lightly floured surface until it is slightly larger than the base of the tart tin (base measurement 35cm x 13cm ... place tart tin on top of rolled out pastry to check size)
The pastry should be firm enough for you to be able to place one hand under one end of the pastry, and lift the other end of the pastry with your second hand
Place pastry into tart tin
Lift the edges of the pastry and gently place the pastry into the base and corners of the tin, using your fingers to lightly press the pastry into the tin’s fluted edges leaving a slight overhang
Trim the top of the pastry by pressing your fingers onto the overhang which will give you a nice even trim
Place tin onto a baking tray, dock with a fork, and refrigerate for 30 minutes
Preheat oven to 180 degrees fan forced, and place rack into middle of oven
Fill pie shell with baking paper filled with baking beads or rice, making sure you go right to the top of the pastry edge (this helps to support the sides so that the pastry doesn’t “drop”
Bake pie shell 20 minutes
Remove from oven, and remove baking paper and beads
Return pastry to the oven and bake for a further 10 to 15 minutes until the base looks “cooked” and is a golden colour (it takes an extra 15 minutes in my oven)
Remove from oven and cool completely before making filling
