Watkins Baking Powder in CT?
Watkins has a great line of products (mostly natural & organic) They mostly have direct selling reps (like Avon & Amway) That is probably who you purchased from at the Xmas Show. I've seen a few of their products at Whole Foods (but not the Baking Powder) There are several reps who sell online.
There is a representative in Massachusetts. You can find if there is a local rep by calling watkins direct (1-800-928-5467)
P.S. Their gravy mixes are fantastic too !
