If your dough is too sticky you can refrigerate it for 10-20 minutes prior to rolling into balls feel free to coat hands in flour prior to rolling, just don't overdo it as it will cause dry cookies and cracking I used bobs red mill 1:1 baking flour and what I recommend for this recipe. This contains rice flour making it a tad drier than gluten free all purpose flour. If you're using gluten free all purpose flour your dough will be more sticky so I would definitely refrigerate your dough.
