For those of us with celiac disease this product is a lifesaver and what could be better than getting it at almost half the price of the grocery or health food store! I love McCann's instant oatmeal - all flavors!!! Thanks, Abby

This mix makes GREAT belgian waffles. We tried biscuits and pancakes and we do far better form scratch with a standard GF flour. It does make seriously great waffles though, and we go GF/DF on these. The waffles freeze extremely well and reheat in the toaster quite nicely.

I was disappointed by these eucalyptus leaves - they have a stale, oregano-like smell. Ask your local florist to get you some fresh leaves!
