Pretty simple really.
Pastry - a rough puff
Beef (skirt if you can get it)
Salt and pepper.
Eggwash for glaze
Chop or grate the potato, swede and onion and set aside, cut the beef into small strips/cubes.
Roll out your pastry, making sure that its not too thin or it will tear when you try to encase the filling. Use a plate or something round as a guide to cut it into a circle.
Add a handfull of potato, in the centre then add swede and then onion in reducing amounts. Add the beef on the top (the juices will then run down through the rest of the filling as it cooks) and some salt and pepper.
Take a pastry brush and brush half the outside of the circle with eggwash, grab the top and bottom of the circle and bring them together over the top of the filling, then work along folding the crimps until you get to the end, where you fold it over itself to seal.
Brush with eggwash and stick in the oven at 170 ish for about an hour (depending on how big they are)
Once cooked, the will stay hot for quite some time.
For extra calories, when eating open along the top and add a couple of knobs of butter....
Should be served with a big mug of milky tea.
