Preheat your oven to 200°C/400°F/Gas 6. Place your butter/margarine in the freezer for about 15 minutes to harden Sieve your ﬂour into a bowl. Grate the hard butter/ margarine into the ﬂ our. You may need a little ﬂ our on your ﬁngers for this. Using a knife, mix grated butter/margarine into ﬂ our. Add sufficient water and mix to a soft dough with the knife. Turn onto a ﬂoured board and knead lightly. Roll out half the pastry to the size of an oven proof plate.
Arrange your apples on the pastry. Sprinkle with sugar to sweeten. Roll the remaining pastry to cover the apples. Dampen the edge of base pastry with cold water to seal. Press top pastry over apples to make the tart. Seal the edges by using the back of a knife to form a crust. Then cut at 1”/3cm intervals to form a scalloped edge, if liked! Put a cut on top of the pastry to allow steam to escape and bake for 25-35 minutes approx.
