what does book fold mean in culinary terms?!

Best Answer - Chosen by Voters

A book fold is a baking term, used when preparing dough for making puff pastry.

The different types of turns control the shape of the dough that you're making.

I'll post a link to a site that talks about making puff pastry. It mentions and explains the book fold.

Hope this helps;

The problem is culinary terms, the issue is not book fold
