Sift the flour into a large mixing bowl.

Mix in the flour.

Add the butter and rub into the flour until the mixture resembles wet sand.

Sprinkle 2 tablespoons of the water and mix in using a round-bladed knife. Add more water only if necessary.

Bring everything together with a light touch to form a firm dough. Handle it as little as possible.

Wrap the ball of dough in cling film and chill for at least 30 minutes before using.
