Baking with a lot of rye is a little different. When I say a lot of rye, I mean a lot. We are talking about at least 50%.
When you start to reach 70% rye, you can just as well forget all about dough strength and stretch and fold.
The dough feels like concrete, no matter what you do.
And trying to get an open crumb is like hoping for George R.R. Martin to finish Winds of winter.
It probably won’t happen.
