Step 1: Sift the flour in a mixing bowl and add the salt.
Step 2: Put in the cubes of butter.
Step 3: Rub it all together using the tips of your fingers until it looks and feels like breadcrumbs.
Step 4: Stir in the water until the dough binds together (using a knife helps and you may find that you do not need all of the water).
Step 5: Cut your ball of dough in half, and put one half aside.
Step 6: Roll out the dough to make a large circular shape and put on to the bottom of your pie dish, so that it covers the edges too.
Step 7: Spoon the tinned steak on top of this and spread evenly.
Step 8: Roll out the other half of the dough to make the lid, and put on top. Pinch the edges together to seal.
Step 9: Prick the lid several times with a fork.
Step 10: Place in the oven at about 180 degrees (fan oven) for 20-25 minutes.
Step 13: (Note: once you’ve binded the dough together, you can break a little piece off and leave to one side to roll out and cut in to a decoration to put on top at the end. E.g. a leaf / love heart)
