					  Put the flour into a food 
					  mixer fitted with a dough hook and add the salt to one 
					  side of the bowl and the yeast to the other. Add the milk 
					  and eggs and mix until well combined. Add the butter, bit 
					  by bit, as you mix for a further 5 mins. It's important to 
					  add the butter very gradually. 
- 
					  Tip the dough into an oiled, 
					  large plastic container or bowl and cover with an oiled 
					  lid or cling film. This dough can rise greatly and needs 
					  room to expand. Leave until at least doubled in size - at 
					  least 1 hour. 
- 
					  Tip the risen dough out onto a 
					  lightly floured surface. Without knocking back, roll the 
					  dough out to a rectangle, just under 1.5cm thick, with a 
					  long side facing you. Lay the Parma ham slices over the 
					  dough. Tear the mozzarella into pieces and scatter over 
					  the ham. Sprinkle the basil on top. 
- 
					  Roll up the dough from the 
					  long side furthest from you to enclose the filling. Roll 
					  into a sausage, 40-50cm long. Cut down the entire length 
					  of the roll, to reveal the filling. Hold the pieces firmly 
					  at each end and twist quite tightly together, moving your 
					  hands in opposite directions. Now coil the twisted dough 
					  into a circle and press the ends firmly together. 
- 
					  Place the crown on a lined 
					  baking tray. Put the tray inside a roomy plastic bag and 
					  leave to prove for 1-1h 30 mins until at least doubled in 
					  size. 
- 
					  Heat your oven to 200C. Brush 
					  the top of the couronne with beaten egg and scatter with 
					  the parmesan. Bake in the oven for 25 mins until golden 
					  brown. Leave to cool slightly and serve warm or cold.
