I have tried to practice with the cookie press. Maybe it's just me, but I could not get the cookie dough to come off of the press and stick onto the stone. I think I did it just as the directions said. I made a cookie spritz recipe, so the dough was soft. It was coming out of the press, just not sticking to the stone, so it fell all apart when I tried to peel it off. Is there a trick to this?
