The dough for these cookies is quite sticky but when chilled you should be able to shape it into a ball after scooping.  I used a round measuring spoon to scoop the dough to give them a nice round shape whilst scooping. Then I’ve rolled them in the palms of my hands until perfectly round. If it gets too sticky try running your hands under cold water, dry them, and try again. Warm hands will melt the butter in the dough and make it even stickier. If the dough can’t be formed into a ball from the off, pop it back in the fridge for a bit longer to let it cool down further. This way, the butter in the dough will harden, making it easier to shape.
