Shirl, I have made quite a bit of sourdough bread - and you are correct, if it was easy everyone would do it!
I'll dig around and see if I can find a photo of one of my loaves, and also the recipe I used.
I had a lot of trial-and-errors (LOL -
all errors!) before I broke down and purchased a scale similar to the one that Velda describes, and was more careful in evaluating my starter - and in measuring my four in grams, rather than by cups.
Two things to consider when making sourdough:
First thing: Measuring the flour in grams is
critically important. Why? Because "cups" measure
volume, grams measure
weight. Different kinds, and different brands of flour can vary in density (volume-per-cup) - in other words, a cup of one type or brand of flour can vary a lot - a cup of one can be heavier - thus more dense. Or lighter - thus less dense - than the another.
This can even be true of the same brand of flour, of the same type (bread flour, pastry flour, all-purpose flour, etc.). It can depend on how the flour was milled, and how it was stored.
In a lot of cooking things, this cups-vs-grams doesn't really matter too much. When making sourdough bread, it
definitely does.
When measuring flour by grams, - a gram of flour is a gram of flour is a gram of flour. In other words, measuring flour by grams is a lot more accurate than measuring flour by cups.
Second thing: The "starter" used for sourdough must be so bubbly and active that it will often overflow the jar that it is "living" in. When it is "fed", it should double by volume in a couple of hours. And, yes, sourdough starter is most definitely "alive", it is a living, breathing, yeast culture.
I would also disagree with Sheila a bit here. Traditionally, sourdough bread is not baked in bread pans. It is formed into "rounds" or "baguettes" or oblongs, and baked that way. If the dough is the correct density, and elasticity, it will hold it's shape - and rise - without the aid of a bread pan.
However, one must "score" the top of the unbaked loaf with a very sharp knife, or a razor blade (I always used a razor blade), so that the dough can expand as it bakes.
Now I'm off to find that recipe!
