I have to try this one. I love rye bread. It is really the only bread that I eat since I try to avoid wheat breads. As a former New Yorker I agree with Kalya on the caraway seeds.
I sometimes buy a bread from a small commercial bakery called Bohdi's they call it wupper light. it is a combination of rye and lupin. similar tasting to rye bread but a bit heavier. It has a fairly high protein contenet from the lupins.
