I had difficulty finding Xanthan Gum in our Coles Supermarket, I found it in Coles Online and still could not find it in the shop. A super tall male assitant found it on the top shelf.
It was worth finding. I used it for peanut biscuits and made some coconut flour bread rolls and it really adds the glue. It is supposed to be 1 teasp per cup of non wheat flour, but I used double for coconut flour. There is a niche market out there for someone who wants to sell nut flour with X in it.
It is easy to use and should save all those eggs that people use for glue in nut and flax flours.
