Fit the Food Processing Attachment with the knife blade. Place the water and butter in a saucepan and heat gently until the butter melts, and then bring to the boil.

Remove from the heat and tip in the flour. Beat with a wooden spoon until combined. Return to the heat and cook over a low heat for a few seconds until the mixture leaves the sides of the pan to form a ball. Do not over-beat.

Transfer to the Food Processing Attachment. Turn on to minimum speed and gradually pour the eggs through the feed tube. Process until just mixed and the pastry forms a stiff, glossy paste. Do not overprocess or it will become too thin. Use as required.
