1. 1To make the dough, rub the butter into the flour and then add the egg white and half the yolk (keep the rest), vinegar, a pinch of salt and enough cold water to make a soft dough.
2. 2Knead on a floured surface until smooth and then wrap and rest for 30 minutes.
3. 3Heat the ovenHeat the oven to 180c/fan 160c/gas 4. Trim the green ends of the spring onions and then finely slice the rest. Get a little oil hot in a pan and fry them gently until soft but not browned.
4. 4Add the chilli and garlic, stir and then add the prawns and cook until they are opaque. Season well. Scoop out the prawns and bubble the juices until they thicken, then add back the prawns.
5. 5Divide the empanada dough into eight balls and roll out to thin circles on a floured surface. Put some filling on one half of the dough, sprinkle the feta on top and fold the other half over.
6. 6Trim the edge and then fold and crimp the dough together so the empanada is tightly sealed, put it on an oiled baking sheet either on its side or sitting on its un-crimped edge like a cornish pasty.
7. 7Repeat with the remaining dough and mixture. Mix the leftover egg yolk with a splash of water and brush the top of the empanadas.
8. 8BakeBake in the oven for 30 minutes or until golden and slightly crisp around the edges.
