Spread one portion (100 grams ) of the butter to form a 5 x5 inch square on parchment and chill.

Meanwhile , on a clean surface , measure out the flour , make a well in the centre. Add the water and salt.(pic 1)

Stir the salt into the water .

Add the remaining butter , cut into cubes, to the flour.(pic 2)

Using your fingers , rub the butter , water and flour together to combine. You can also use a pastry scraper.Bring the crumbs together in a rough dough. (pic 3)

Wrap and chill for one hour.

After the chilling ,on a floured surface, roll out the dough into a rectangle about 5 x 15 inches.

Place the chilled butter slab in the centre and bring both short ends of the dough rectangle towards the centre and press to seal. You will now have an envelope of dough with butter exposed on two ends.(pic 4-6)

Roll out this envelope into a rectangle again of about 5 x 15 inches , trying to keep the edges as straight as possible.(pic 7)

Starting from one short end, fold one third onto the centre. (pic 8)

Then fold the other third on top (like folding a letter).This is one turn.(pic 9)

Again , roll into a rectangle and fold as above . This is your second turn.(pic 7-9)
