Babka isn't complicated. But enriched dough follows different rules than the lean loaves most of us start with, and if you don't know those rules going in, the filling slides, the layers blur, and the interior comes out gummy instead of distinct.
This video covers all of it. How the dough behaves. How to handle different fillings so they stay put. Why inclusion size and moisture content matter more than most recipes tell you. And why the refrigerator is doing real work on your dough overnight, not just buying you time.
That last part ties directly into something I covered in depth on YouTube already. If you want the full science on what cold fermentation is actually doing, that video is here: https://youtu.be/WLtlnqGIYi0 Please, like and subscribe while you're there.
Watch it. Then go mix your dough.
