It's okay but it does not have a rich chocolatey taste. I actually find it to have a funky taste, can't quite figure it out.

First off,  let me state that I am not a fan of decaffeinated coffee of any type.  But I often have guests over who ask for de-caf, so I gave this a try.  While I agree with some other reviewers who have stated that there is a certain "different" taste about this blend, for me, it was not a bitter taste, but instead, a good, strong flavor that mimicked the strong (real) coffee taste I enjoy.  I had a second cup, and the flavor grew on me even more, and I thought: "it really is delicious for a decaf."  The aroma isn't truly satisfying (why does this always happen with decaf?) but I think many decaf drinkers will be used to that lack.  The package had to be snipped open with scissors --this is tightly packed!-- and then I just poured it into a zip loc for storage in the fridge.  I'll stick with regular coffee, but I'm sure my de-caf loving friends will enjoy this.

The first time I tried this product to make pancakes, I thought it was terrible.  I made it according to the directions and used the "right" measuring cups for liquid and dry ingredients, but found that the batter came out thin and the texture was gummy.  Then, one day when I was visiting my mother, she decided to make pancakes, and since I am GF, she had bought this mix for me (not knowing I had already hated it).  I saw that she measured the ingredients "incorrectly" as she used the same measuring cup (generally used to measure liquids) for both the dry and the liquid ingredients.  She also used a whisk to mix the ingredients.  Amazingly enough, the pancakes came out fluffy, and I really liked it.  In fact, it is my favorite gluten free pancake mix so far.  Having said that, both my husband and I are of the opinion that this product still has a bit of the gritty texture that is present in many gf products.  However, it is the best pancake mix that I have found so far.
