I use arrowroot in the place of cornstarch for thickening stirfries and gravies. (Don't use flour at all due to celiac condition.) Lynnet Thanks...when I did a web search for arrowroot, I got lots of cassava/tapioca info. It seems arrowroot can also be derived from cassava (this is what I was confused about). So, where can I buy arrowroot? I couldn't find it at the HFS, do you know of anyplace on web? I checked GFPantry and GFmall, again searched for arrowroot, brought up tapioca. Since I do have some tapioca flour, and I feel fine about using it, do you (anyone) suppose that it would work in place of arrowroot until I can actually get the arrowroot, for the arrowroot bread (cracker) recipe at paleofood.com? Thanks, Stacie
