...comin' thru the rye.
Rye breads are notoriously difficult to make from scratch and a lot of so-called "Jewish Rye's" sold in the US are less than 10% rye flour and depend on caraway seeds and caramel coloring to distinguish themselves from other pan breads.
Rye flour produces little or no gluten which is the protein that traps fermentation gases and makes wheat breads rise. Rye doughs are also notoriously sticky, slack and difficult to shape and mold. If you really want to learn how to make them, since you are very near one of the best artisan bread bakeries in the US, Zingerman's in Ann Arbor, go there and see if you can't volunteer for a week or so and get at least a feel for working with rye.
I teach baking in a couple of local colleges and I always tell my beginning students that rye breads and sourdough breads are really advanced baking subjects and would be better learned after you are well practiced in conventional wheat flour doughs. Germany produces the largest and best variety of rye breads in the world and they actually legislate breads by amount or percentage of rye flour in the dough, ranging from 100% (REAL Pumpernickel which goes into special coffers as a batter and takes up to 14 hours to bake during which time the starches caramelize and give the bread it's distinctive dark color) to 1 %.
If you want to try to teach yourself how to bake with rye and how to work with sourdoughs, I would recommend you find a copy of Nancy Silverton's "Breads from the La Brea Bakery". She's someone I've worked with and think is very talented, but, more importantly, the book is well written and the recipes work. One of the biggest problems you are going to have is procuring the right rye flour as there are no standards for different grades of rye flour as there are in Germany and in France. You may be lucky enough to find White Rye, Medium Rye and Dark Rye as well as "Pumpernickel Flour" and "Rye chops" in a good local organic market, but make sure that the flours are fresh. Rye will turn rancid if left at room temperature for more than a couple of weeks so try to go to a market that has a lot of turnover. The King Arthur Flour catalogue may be a good resource; I've bought a lot of good wheat flour from them, but no rye.
Also, be aware that rye flour is unusually susceptible to contamination by a type of mold called ergot. Ergot is what they start with to synthesize LSD, so you can imagine what ergot poisoning can be like. It is widely thought that whole towns went mad and died in the Middle Ages from eating from silos holding inoculated grain. The last case of documented ergotamine poisoning was from a rye-bread sandwich eaten by a doctor, no less at NYU medical school in the Seventies.
I will look for some easy rye formula to post here, but as with most bread baking, it's not so much the formula as the technique which will require some practice and lots and lots of patience. I can give you a good tip as well: a dishwasher makes a GREAT proof-box. Run this dishwasher through 1 fill and cycle, then put your dough inside. The steam from the hot water is perfect for rye breads. Remember that humidity is almost more important than heat in working with yeast doughs.
