Just happened to see this in catching up, after being away from a computer for a week!
Have you made injera? Are you looking for a recipe? Sundays at Moosewood has a whole section on it, explaining exactly how to do it and what it is. I can look it up if you need it. From what I can tell, teff is pretty much essential; but maybe something else will say it isn't. I can now find whole teff in my local health food store in Nova Scotia, Canada, and I couldn't a few years ago. I also have a flour mill, so I intend to grind it to make the flour (which I still can't find, BTW).
From what I remember, injera is a flatbread, a pancakey-thing, that you let sit for a few days to make it "sourdough". I've had it many times at Ethiopian restaurants and I agree it's the best thing ever. It's used to scoop up (the world's most delicious) food there. Let me know if you think I can help!
