I recently found brown bread flour from Doves Farm. I use their flours in most of my gluten free baking. The quality is always excellent.
To make gluten free brown bread, it requires a mix of a few different flour types with lots of trials so to find one that’s been created, tested and is successful is such a joy! It’s great they have taken all the hard work out of trial and error with different flour blends and found the perfect combination!

The first time I made this recipe, I followed it to the letter and it resulted in a totally delicious and authentic brown bread. Such happiness ensued I can’t tell you! After that, I started to add my own twists and each loaf has been perfect.
