Ultimate Sourdough Baguettes - Questions
Today i made this wonderful baguettes from KAF.
here is the link : http://www.kingarthurflour.com/recipes/ultimate-sourdough-baguettes-recipe 
the flavors was great and more importanat it is vary quick receipe.
however, I have several questions about the process.
1. why adding Gluten ? we are not using whole wheat or Rye ? Is it typical for Baguettes ?
2. why using Sourdough and also Yeasts ? just to speed up the rise ? any drawback for that ?
3. the baking does not require steam ? Is it also typical for Baguettes ? mybe we dont want it to rise to much in the oven ?
