I added arrowroot powder to these crackers to "lighten up the color" of the final product (flax meal and nut meals bake darker crackers). I think this may be my only recipe that calls for it. I had noticed a lot of Paleo cooks' photos of baked goods on the net that used it as a flour sub with other LC flours, came out "whiter" products. That's the only reason, really. But since it's a bit carby, I didn't add much.
