I've begun making bread and have been experimenting with sourdough. I've
been trying not to use any additional yeast -- just the sourdough itself. How
can I control the taste of sourdough and how can I control the strength in
terms of rising times?
Sourdough needs to feed on flour. You can control the acidity because
the desirable thing about a sourdough is how the acidity works. There are
many factors involved, but if you feed it frequently with flour it is going to
generally be more mellow than if you just let it produce more and more acid.
One of the last steps in fermentation is acid. You don't want it to keep
fermenting until it becomes extremely acidic. It's a misunderstanding that
sourdough bread has to be so sour that you pucker. The most traditional
method of making bread throughout the world is a flour and water mixture that
ferments from wild yeast and becomes the "yeast" for your loaf. So keep
adding flour and water to it about once a week.
Does it make a difference what I use to start the sourdough? I'm using a
recipe that calls for grapes.
That recipe would tend to have an acid overtone to it. But if that's a
taste you like, that's fine. There's no right or wrong about it. But I
suggest you check out a couple books that tell you other methods. Take a look
at Dan Leader's By Bread Alone (published by William Morrow and Company) and
The Village Baker by Joe Ortiz (published by Ten Speed Press). Each book
will give you different ways to make sourdough bread -- there are many and they
are all fascinating to play with!
