Of course the first link will be biased as it is from the company's website! The company started in Turner's Falls MA, now also has opened a production in Vietnam.

My husband brought this package home from the grocery store and we had it last night. Very good and a nice change. Of course after dinner, I did all the digging I could, not convinced yet that I shouldn't buy it again!
