Line one large or two medium non-stick baking sheets or use a regular sheet with parchment paper.
Add the milk to a bowl and stir in the yeast and sugar. Allow to sit for 3-5 minutes (maybe more) until you start to see it bubble a little.
To a mixing bowl add the flour, salt, spices and currants. Mix well. Make a well in the center, add the milk and yeast, butter and beaten eggs. Use a spoon and stir to incorporate the liquids into the flour. When the dough comes together, use your hands to make the dough to a large ball. It will be sticky. Turn the dough out onto a floured surface and knead for about 5 minutes until smooth and elastic.
Place in an oiled bowl, cover with a towel and leave in a warm place for about 45 mins to rise.
Turn out the dough onto a floured surface and knead lightly for a few minutes until smooth. Divide the dough into 12 balls and shape each into a bun that is a flat round.
Place evenly spaced onto the baking sheet and cover loosely with a towel. Leave in a warm place for 30 minutes until they double in size.
Preheat oven to 400°F /200°C.
Brush the tops of the buns with the milk. Bake for 15-20 minutes until golden brown (time may vary depending on your oven).
