Place all the ingredients in the bread maker in the order listed - apart from the 150g chilled butter.

Set off using menu '19' on the Panasonic bread maker. The program should run for 2 hours and 20 minutes.

When the bread maker has finished, roll the dough to a 20cm x 25cm rectangle.

Divide the chilled butter into 3 equal portions. Dot one portion over the top two thirds of the dough.

Fold the bottom one third up and the top one third down, sealing the edges with a rolling pin. Turn the dough so that the folded edge is on the side.

Roll out to an oblong, dot the second portion of butter and continue as before. Repeat with the third portion.

Cover and allow the dough to rest in the refrigerator for 30 mins.

Repeat the rolling three more times, cover and chill for 30 mins.

Roll out the pastry and divide into four squares. Cut each square into two triangles. Reroll each triangle long and thin.

Loosely roll up each triangle towards the point, finishing with tip underneath. Curve into a crescent shape.

Place on a greased baking tray. Allow to prove at 40C/105F until doubled in size (approx. 20 minutes)

Brush with beaten egg and bake in a preheated oven at 200C/435F/Gas Mark 7 for 15 mins or until crisp and well browned.
