This dough is definitely sticky, but there are a couple of ways you can prevent it from sticking to your hands and rolling pin. For your hands, run them under cold water, and shake off the excess water. Then when you shape your dough into the disc, it'll help stop it from sticking to your hands. When rolling the dough out with a rolling pin, roll it out on parchment paper and use plastic wrap to separate the dough and the rolling pin.
