Ex Input:
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.

Ex Output:

Thought this might be a nice alternative to use with my favorite coffee, but was sadly disappointed.  It leaked all over - no matter what we tried and the coffee was weak, machine clogged with most attempts and water wouldn't brew thru.  At times the cup even melted a little - leaving a nasty taste in the coffee.  Go with the greener alternative and try the ekobrew - much better results and no waste.

Ex Output:
