I have continued to play with my formula for what I call "San Joaquin Soudough." This continuing series of experiments started with my curiosity as to whether the baguette formula of Anis Bouabsa could be applied to other types of bread than baguettes. The short answer is, of course, "yes."
The basic approach I have been using is described in detail in the following blog entry:
http://www.thefreshloaf.com/node/8454/pain-de-campagne
The present variation used 10% KAF White Whole Wheat flour, 90% KAF Bread flour and a slightly higher hydration - 76%. The techniques for mixing, fermentation, etc. were as I have described before. So, the ingredients were:
Ripe 65% hydration sourdough starter....100 gms
Water........................................................380 gms
KAF Bread Flour.........................................450 gms
KAF White Whole Wheat Flour...................50 gms
Sea Salt.........................................................10 gms
Instant Yeast................................................1/4 tsp
The combined effect of the different flours and the higher hydration was to yield a dramatically different bread with a much more open crumb structure - really ciabatta-like.
Now, I did bake these loaves under an aluminum foil roasting pan for the first 12 minutes and then for another 18 minutes uncovered. The oven spring was massive. My scoring was obliterated. Examination of the crust coloration of the bloom revealed that the bloom occurred very early in the bake and very rapidly. (The coloration was even and not different from the rest of the crust. See my Scoring Tutorial in the TFL Handbook for further explanation.)
With the higher hydration and covered baking, the crust softened quickly during cooling. The crumb was like a good ciabatta - very tender yet still chewy. The taste is very mildly sour, even on the day after baking. It made a delicious sandwich with Toscano salami, Beaver Brand Sweet Hot mustard and lettuce. (Sorry, Mini. It definitely would drip mayonnaise in your lap.)
This bread presented me with a number of surprises, but I'm far from disappointed. I'm happy to have a "new" bread in my repertoire.
