On a clean bench combine flour, baking powder and salt, make a well in the centre, add butter and milk. Gradually mixing together until a dough forms, knead for a couple of minutes. At this stage if too dry add some more milk, if too wet add some more flour, until a nice dough consistency.
Lightly dust with some flour and then place a tea towel over your dough and let it rest.
Making the filling.
In a saucepan heat your oil up on a medium heat, sautee off the diced onions until translucent, add your garlic and then your mince meat. Break up the mince just like you would for a bolognaise sauce, add your seasoning, salt and pepper, then your cummin and paprika. Cook and simmer for about 5-10 minutes. Turn off and let it cool.
Portion a piece of dough into a ball to about 200g, then roll it out using a rolling pin and some flour on a bench to a size of about your hand.
Place about 3 tbspn of cold mince in the centre, add a quarter of a boiled egg a couple of pieces of olives and a pinch of sultanas.
Brush a bit of egg wash on half the dough and fold the dough over like a pastie. Then twist and fold the edges together.
Place on a oiled tray and baste with some egg wash.
Bake for about 15-25 minutes, or until golden brown.
