Hi again! JMM-uc - I've been making this recipe for years and it has never been bitter. I think it really must be the flour you are using. Please try a GFE flour like King Arthur brand and see how you like it before you give up. Also, try using some honey instead of around half of the sugar. It may help.
Please let me know how it goes. Thanks to all who have tried this recipe and loved it!!
