Spinning buckwheat crepes

Hello, I've been making buckwheat crepes for a long time in cast iron pan, pivoting the pan in the air to spread the batter all over. But now, I have a cast-iron large griddle where I can cook multiple crepes at the same time! To spread the crepes, I bought a wooden spreader to spin them. But it doesn't work as well as with classic white flour pancakes. As soon as i start spinning, lumps of half-cooked dough start sticking to my spreader, shredding parts of the crepe and creating a mess. Any idea what might be the problem, and how to solve it? Thanks everyone. submitted by /u/philmarois
