Step 1:
To start, take the frozen pastry out to defrost a few hours prior to making the pie or alternatively you can defrost it in the microwave. Step 2:
Peel the potatoes, half them and add to a pan of salted water. Bring to a rolling boil. Boil the potatoes until they become soft enough to slide a sharp knife through. Step 3:
Whilst boiling the potatoes, in a seperate pan, empty the can(s) of stewing steak and heat gently until the gravy becomes more fluid (you can add a touch of water to loosen the gravy). Step 4:
Preheat an oven to 200 degrees. Step 5:
When the potatoes are done, drain and empty them into an oven proof dish. Top with the stewing steak and gravy and then top with the pastry. Step 6:
Brush the pastry with an egg yolk and place in the oven until the pastry is golden. Step 8:
Serve with veg and gravy if you wish.
