My daughter was diagnosed with celiac about 2 years ago, and has gone without pancakes ever since...until I happened to come across this at the grocery store. Really wasn't expecting good results - but it's very good! The non-celiac members of the family even prefer the gf version to the regular! Try it!
Output:
Positive
