*Because this dough is so tender, it might not fully cooperate when you try to transfer it but DONT WORRY! You can easily patch any breaks etc as you are fitting the dough into the tart pan.
If you are really having issues here, you can do one of two things:
1) reform the dough into a disc and start over (refrigerating newly formed disc first)
2) press the dough into the pan as if it were a shortbread cookie dough - this is a totally acceptable method but it is hard to get the thickness as even as rolling so I usually opt for patching but it is completely up to you!
