Serves: 1 (900g) loaf1) Combine water and sugar in a small bowl and sprinkle the yeast over the top. Set aside until foamy, about 8 minutes.
2) Put 150g of the flour in a large bowl and make a well in the center. Whisk together the honey, one whole egg, the yolks, olive oil and salt in a small bowl and pour into the well. Stir to combine. Add yeast mixture, remaining 450g flour and currants and stir to make a soft, shaggy dough. Turn the dough onto a lightly floured surface and knead until soft and supple, about 10 minutes.

4) Turn the dough onto a clean work surface and divide into 3 equal pieces. Roll and stretch each piece into a rope 30-38cm long. Arrange the ropes side by side vertically on the work surface. Starting at the far end, pinch the the ropes together and then plait to the end.
5) Transfer the loaf to the prepared baking sheet and neatly tuck both ends under. Cover with the tea towel and set aside to rise until doubled, about 1 hour.
