To prepare your butter, place between two pieces of greaseproof paper and fold into a square of 15 cm / 6 inches.
Tap lightly with a rolling pin to flatten until you can roll it evenly all the way to the edges.
Place into the fridge to firm up slightly whilst you make the dough.
Place the flour and water into a large bowl and stir together to form your dough.
Set aside to rest for 15 minutes.
Lightly dust your work surface with flour and roll the dough out to a 28 centimeter / 11 inch square.
Remove the butter from the fridge 5 minutes before placing onto the dough, it should be chilled, but not super firm.
Place the butter diagonally in the center of the dough so you have the square dough with a diamond butter square in the center.
Fold the corners of the dough over like you would if you create a square envelope to fully cover the butter, ensure you cannot see any of it once the dough is pinched closed.
Roll the dough out in one direction to a rectangle and then fold in 3 to a wide rectangle.
Cover and place the dough in the fridge for 20 minutes to chill.
Remove from the fridge and roll the dough out to a rectangle in one direction and then fold in 3 to a wide rectangle.
Cover and return to the fridge for 20 minutes to chill.
Remove from the fridge and roll out to ¼ inch thickness approximately 30 centimeters / 12 inches wide and brush the surface with water.
Roll into a log, trimming the edges and slicing into 12 even pieces, approximately 1 inch wide.
Place into your muffin tray and allow to rest for 10 minutes.
Lightly wet your fingertips and press the dough into your muffin tin firmly until it is just above the lip of your tin. Set aside.
