From Andrew Janjigian's Bread Basket Newsletter (which you should really subscribe to):

This week's basket holds three items related to one of my favorite flour millers, Washington State's Cairnspring Mills, which has made appearances in a few different venues recently, including two in the past month alone.

It’s a quick little read, and links to three other stores about Cairnspring. The timing is nice as I just picked up another 100lbs of flour from them.
