at my work we sometimes get requests for gluten free items. i usually offer a flourless chocolate cake, or a crustless cheesecake. but im noticing that Bobs Redmill, and King Arthur Flour offer Gluten Free All Purpose flour. Has anyone used a flour mix like this? do i just use it in a recipe that calls for All Purpose flour? Im guess im going to purchase some and experiment, so if anyone has any tips , i'd greatly appreciate it! im looking to make things like: brownies, pie crust, cookies....etc.
