Two attempts and I can’t get a decent batter consistency. It ends up as a dough with the very absorbent, granular manioc flour…and a dough simply won’t puff up like it should. So I’m going to do what my trusted source made me swear I wouldn’t do: use tapioca flour. I can see no other way forward. Sorry, (DELETED)! The good new is that if I get it to work more of you will be able to try it, since tapioca flour is a more common ingredient.
