Query: Excellent GF Flour Substitute

This is a seriously good flour. The ratios are balanced very nicely. It is reliable.I had read a previous reviewer who talked about buying the bulk flours listed and mixing your own. Yeah, that's all right & good...if you can guarantee it isn't contaminated. I used to buy in bulk till I watched this lady grab the regular flour scoop & get some potato flour. Now we eat GF for other reasons than Celiac. However, for some this could be bad. Other buying in bulk issue is finding the right ratio. This flour has figured out the balance & is worth it. We don't eat tons of baked goods, so this is a good deal.I have used this in a 1:1 ratio with Pamela's Baking Mix to make Nestle's Tollhouse Cookies. Nobody could tell the difference between the GF cookies & regular Tollhouse.Makes this flour the winner.
