mark,if you have a sweet tooth you can use zylitol, a sweetener from health food stores and you can have vinegar but apple cider vinegar, you can buy this from supermarkets.
brown rice flour is okay for me, i only use a bit and add ground nuts and flax seeds to mix in the flour for certain recipes. if you would like some recipes heres a good site, go to the forum.
