I dropped by Whole Foods Market today here in Oklahoma. I went in looking for Whole Rye Kernels and wasn't expecting to find them. To my surprise they have them and at an excellent price: 99 cents a pound if I recall--or maybe more but whatever price it was I thought it was pretty fair at the time. I picked up three pounds for some pumpernickel bread. I'll be smashing, chopping, grinding and soaking portions of them myself as I couldn't find any chopped or cracked kernels there at the store.
I also picked up my first King Arthur Flours at like $4.39 a 5lb bag: Bread, All Purpose, and Whole Wheat flours. Unfortnuately they did not have any King Arthur Rye flour there or else I would of bought it; (Hodgson Mill Rye seems really good so I'll just stick with it.)
They also had some whole spelt kernels there as well as ground up spelt. I bought a pound of the spelt kernels in case I ever want to add it to a loaf. I don't have any loaf in mind but it just seemed cool to buy this ancient wheat :)
There is a wealth of information about spelt in this website. Try spelt in the search field. You will find hours of interesting reading.
As Minioven once said, "spelt and rye like each other". A good complement to your rye flour.
