20mlcold waterif needed (sometimes I don't need it)
Instructions
Place the butter, egg & sugar in a large bowl & cream with a wooden spoon, i.e., mix it up.
Sprinkle the flour over and mix it into the butter mixture either still with the spoon or as I do it, with your fingertips. Gently, just with your fingertips! No kneading or squeezing.
Bring it all together, still gently, adding a little of the cold water if you need it.
Knead it just a handful (max 5!) times with the palm of your hands to smooth it out.
Wrap with clingfilm for 30 minutes before rolling it out.
