One of the reactions I get when talking about gluten, dairy, sugar and yeast free cooking is 'where do you get the ingredients' or 'isn't it hard to find ....'. So here's where I find what I need.  You can find in many local health food shops but if you don't have time to get there here's where you can get it online. If you do have any other great sites please do let me know and i'll checkout and post.
