<<Disclaimer: Verify this information before applying it to your situation.>> Hi I just wanted to introduce myself - I am the mother of a 4 year old boy with autism, Connor, who is just starting a GF diet. We live in London. I am sure that this point has been covered before but for the benefit of a newbie, perhaps someone can tell me the difference between Potato Flour and Potato Starch. I can't seem to find a supplier of Potato Starch in the UK, so if anyone can help - I would greatly appreciate it. Thanks Adele
