If you haven't already discovered Gluten Free on a Shoestring by Nicole Hunn, leave this page now and check her out! Following her detailed and specific instructions, and you too will (re)discover the utter joy of baking! Yes, buy a food scale (about $20, so worth it!) Do make your own blends - she makes it so easy. And you will be amazed at the deliciousness you will again be able to create. Taste, texture, all the great stuff you remember and thought were gone for good!
Now, her baguette is a regular in my kitchen, and it makes me so happy!
Notes:
In this post, I provide the basic ingredients, and include my additional comments on how to ensure your baguettes turn out like the picture. Nicole provides lots of extra information about ingredients and substitutions, as well as detailed info about creating your own flour blends (which I highly recommend). Please visit her site for all that info. She recommends two flour bends, Better Batter (a brand I can't get, but she tells you how to make it, and Cup4Cup (which she also tells you how to make at home, even how to alter her mock Better Batter to make mock Cup4Cup.) I have had success with both of her mock blends.
Make sure your butter and egg white are at room temperature. The key to gluten free baking is hydration and having these items at room temperature ensures that they will mix in evenly to help hydrate the dough properly. Without it, your efforts will be a complete waste, which is a shame with these pricey ingredients!
