<<Disclaimer: Verify this information before applying it to your situation.>> 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.
