A while back I posted about a situation with the final dough of a rye recipe not rising, which I at first blamed on proofing at so high a temperature as to kill the yeast. I was then convinced by the ensuing discussion that it was more likely I had just missed the window of expansion and then over-proofed.
I’ve since had a similar experience (though with a lower proofing box temperature so with no suspicion of the heat being a problem), and it has gradually dawned on me that a repeated problem I’ve had with rye doughs is insufficient hydration, and that this may be the real cause. Most of the rye recipes I’ve been making recently have been from The Rye Baker, and it’s become clear to me that my (home milled) rye flour is a lot more thirsty than what Stanley appears to be using. Perhaps dry New England winters vs California climate is a part of this. It’s taken me a while to realize this since rye dough texture varies so much between recipes and it’s hard to describe desired texture with words. It seems a lot harder to get a feel for rye dough texture (espec wrt hydration) than wheat.
This effect becomes proportionally more pronounced the higher the percentage of rye in the recipe (and the two recipes I had this problem with were either 100% rye or close to it).
Also it appears to me that a rye dough with low hydration doesn’t expand very much. It’s funny that I don’t recall seeing this noted anywhere, in any the bread books I’ve read, but it seems like a rather important thing to know. My doughs rarely expanded as much as what Stanley described in his recipes, and I’ve just taken to not worrying about that, but I think this is probably why.
When I maintain my rye starter culture with equal weights of rye and water, it always rises more slowly then my other starter and doesn’t tend to ever make it to doubling in size. I’ve recently taken to using slightly more water and it makes all the difference in the world.
Can anyone else confirm this idea? Is this a well-known “thing” with rye dough? I understand this correlation between hydration and fermentation exists for wheat dough also, but it just seems so much more pronounced with rye.
