I'm wondering, when you gelatinize rye, does the water somehow get "locked up"? I ask because I've been experimenting with rye recipes, and I set out to make a rye bread with 25% whole rye at 65% hydration. I soaked the rye in all the water. When I came to incorporate the rest of the flour the dough was very, very dry. It barely came together, and by the time I realized how dry it was going to be it was almost impossible to add more water.
