I'm a big Juan Valdez colombian fan. This Jamaican stuff doesn't have the kick that I love from coffee. It's sorta flat. Especially for something I spent $75 for two lbs. Goin Back To Colombian (twang twang)

The best thing about this pancake and waffle mix is the can in which it comes.  I really like the convenience of the can and the fact that it reseals easily. The batter cooked up nicely and the texture was OK.  However I was very disappointed in the flavor.  There were stong overtones of chemical flavors. I will be experimenting with my own recipes in the future.
