Seeking recipe ideas for a long acidic fermentation sourdough
I have done much research on TFL and all over the web (two weeks)and I am not seeing the solution to my quest. I have the Hamelman bread book on reserve at the library and I hope it will teach me a lot about how to design a proper recipe, as I see it is often referred to on TFL & elsewhere by skilled bakers.
My wife is increasingly gluten sensitive (GS) and I am trying to emulate a sourdough secret recipe from Bezian's Bakery in San Fran which has a long acidic fermentation, from a week to a month. As a result of at least a 24 hour fermentation, the peptides in gluten are rendered harmless to GS people. Bezian claims that he has people with Celiac Disease eat his bread, and they report no problems. (We are not Celiacs) I have a strong suspicion that if I am able to produce a largely gluten free (GF) sourdough, then my family will be able to tolerate it just fine. An Italian study used a very controlled collection of lactos & yeasts and I believe it was 70% GF flours (like rice flour etc) and 30% rye flour. It seems like a good idea to use mostly or all rye flour because it is not wheat and it contains far less gluten.
Can you give me any pointers on what might be a good start on a 1 week to a 1 month long fermentation sourdough recipe using all or mostly rye flour? I am quite lost in the forest in this regard.
I have two starters in process, and one pair of loaves under my belt > worst bread I've ever made! (the recipe didn't call for a cover, it seems like it would be useful, and it didn't spring much in the final rise, had no oven spring, and took a colossal amount of effort and time) I've begun using ideas from sourdoughbaker.com.au The Medium Rye Old Dough recipe does ferment for over 24 hours, but not for a week and more.
I have had great luck using the 5 Minute Books. And these breads are intended to store in the fridge for a week or more. I wonder if a rye version of their standard recipe might do the trick, but I have my reservations (can't remember why not at this time).
I welcome your ideas.
