On the subject of Bette's Four Flour Blend two questions
popped up as a result of my summary. Renee and Karen asked
how Bette's Four Flour Blend differs from her previous flour mixes,
and since I do not have Bette's latest book "The Gluten-Free Gourmet
Bakes Bread" I was unable to help them with the ratios for the FFB.

I was able to tell them what FFB ingredients are as printed on the
Authentic Foods packet  i.e.: corn starch; tapioca flour; Garfarva
(gabanzo, fava flour) and sorghum flour.  If anyone can help with the
ratios they would prefer to mix their own

As for adding xanthum gum, the Lee family corrected my comment in
summary reminding me that it is not necessary to add xanthum gum for
pastry recipes.
