Weigh the flour and butter into the Thermomix bowl.

Chop 5 sec/sp4.

Add the water and lemon juice and process 4 sec/sp 4.5.

Tip on to a ThermoMat or silpat mat and press together, using the mat to bring the mass into a rectangle shape. I always use a mat to bring the pastry together as I have hot hands!

Wrap in plastic wrap and place in the fridge for at least half an hour.

Sprinkle bench or mat with flour. Roll pastry out to a long thick rectangle, about 10cm x 30cm, short end facing you. Turn over frequently and make sure the pastry isn't sticking to the bench or the mat.

Fold the top 1/3 down and the bottom 1/3 up to meet in the middle.

Fold the bottom over the top. This is called a book fold. Brush off the flour before folding.

Wrap in plastic wrap and place in the fridge for 20 minutes, longer in summer. (Putting it in the freezer is even better)

Place dough onto floured mat. Roll out again to make the rectangle shape, but this time 20cm x 30cm. Fold again and place a fingertip into the dough to mark it as one fold. Refrigerate.

Place a fingertip into the dough to mark it as one fold.

Repeat four more times until you have five fingermarks in the dough.

Rest for an hour or so in the fridge.

When ready to use, roll out and cut to shape.

Press scraps together and refrigerate for re-use.

Best baked at 210 C.
