Default Sourdough chemistry and carbohydrate

*sigh* Of all the things I can't eat right now I miss bread the most
- specifically I miss *my* bread. I've been an intuitive baker for
years and haven't done the extensive research some of y'all have WRT
the chemistry of sourdough. What I'm wondering at this point is, does
the fermentation process reduce the amount of carboyhdrate (starch) in
the bread substantially, or merely convert it to other, equally "bad"
things such as recognizable sugars and such? I'll go forth and read if
somebody can point me at a pertinent source.

Thanks!

On Mon, 18 Jul 2005 15:06:09 GMT, "L, not -L" spewed
forth :

I make the sourdough semolina bread by using half bread flour and half
semolina flour. Semolina is a very hard wheat so doesn't breakdown to sugar
as fast as softer wheat flour. My assumption has been that the easily
broken down starch is process by the sourdough to feed on, leaving the
slower to breakdown starch for me.


What sort of fermentation times do you use? I typically set a 12-hour
sponge, have a 2-3 hour rise for the finished dough followed by a
60-90 minute proof prior to baking. I'm wondering how longer and
shorter ferment times might affect the "bottom line".

Oh, I see -- if you want your sourdough bread to be sour,
you put the dough in the fridge overnight!??

Who told you that?

Some people are making their bread sour by putting their
dough in the fridge. So they think, anyway.

Who is right? What is the truth?

What is "L, not -L" supposed to conjure up? =20

Quite a few years ago I was on the same quest that you are. I'd read that
the carb content of SD bread was significantly lower than "regular" bread.
I thought I'd bookmarked that, but can't seem to locate it at the moment.

If I find it, I'll be dropping it here for you...

big sigh!

Well, Dick, the process is called retarding. You can look it up at

purports
to be the FAQs for this newsgroup; but, that is only one of many =

sources.
To quote from that FAQ - "Retarding simply means putting your loaves =

into
cold storage, the refrigerator, for awhile. This allows you to bake at =

a
later date, early in the morning if you wish, ...


Right, I knew that.

and it affords the microorganisms in your dough a long, slow time to =

Well, I don't exactly know that, and, although it is not altogether =

Nobody ever said that 2 hours rise is enough, but 4 or 5 hours at warm
room temperature could get you a pretty good rise, and a pretty sour and =

I will allow that refrigerated dough is gloppier than non-refrigerated, =

sometimes, if you are lucky, you will get little blisters on the crust =
when
you bake it (or unlucky if you happen to think that little blisters are

You shall be my hero forever! I'm going to set a sponge tomorrow

oven with my own peach preserves. Be damned to the meter!

Hey "Wooly";

Check out: http://www.eap.mcgill.ca/Publications/EAP35.htm. This wasn't
the article I was looking for, but it's a start.

How about you drop me a note off-group, and we can explore this issue
further?

FYI -- Some major SF sourdough bakeries (I won't name which ones) proof
their dough in the refrigerator overnight. One of the better companies
takes 36 hours to make one loaf of bread (including proofing the dough
overnight in the fridge).

This wouldn't be the one with the $50,000 Spanish brick oven with the
rotating floor would it?

Not the tourist place, if that's what you're talking about. The one on
Fisherman's Wharf.

The reason why I won't name them, is because I don't remember their names
offhand.

Boudin is the name of the tourist place. To be honest, I don't even like
their bread. The best sourdough (non-homemade) that I've tasted is from a
little tiny bakery cafe in a little tiny village in France. I befriended
the owner and his family, and every year he sends me some of his bread. And
I send him some of mine.

This has not been my experience so far at all, and in the last few months I
have been experimenting with rather long fridge times. I have found that
different flavors develops in different temps, the "sour" flavor developing
in warmer fermentations. Without first letting room temperature
fermentation, the sour does not really show up at all, a mellower but still
aged flavor is the result. I am currently making bread with no room temp
fermentation whatsoever, all is done in the fridge. This takes a long time
as you can imagine, so when my fresh loaves come out of the oven, I pretty
much get started right away on my next batch for many days later. Straight
dough (a bit firmer than usual, otherwise things get soupy) with small
starter inoculation, mixed up but not really kneaded and put directly in the
fridge, takes a few days to rise. Punch down. Rise and punch down again.
Rise and take out, divide and form boules, return to fridge for final rise,
remove and bake immediately. There are definitely flavors developing in the
fridge in all this time, straight dough breads without fridge retard is not
comparable at all, but it is not sour.
