Step #1
Place the bread mix into a mixing bowl. Add the caster sugar, softened butter, eggs and milk. Mix until a soft dough ball forms.
Step #2
Knead the dough for 5 minutes with minimal dusting flour. The dough will feel soft but will firm up during kneading. Cover the dough with a damp tea towel or lightly oiled plastic and let it rest for 5 minutes.
Step #3
Divide the dough into 8 equal pieces, roll each into a ball and gently flatten the bottoms against the work surface.
Step #4
Arrange the dough balls on a lightly greased baking tray. Cover again and leave to prove in a warm place for 40-50 minutes, or until doubled in size.
Step #5
Carefully remove the cover and brush the dough with the egg yolk and water mixture. Bake in the center of a preheated oven at 210°C (410°F), Gas Mark 6½ for 15-20 minutes until deep golden brown.
Step #6
Remove from the oven and let cool before serving.
