I want to make my own rye crisps like in Gardettos. They're the best part! The company sells bags of just those because they had a huge demand for it.
Bagel chip recipes like these might be a good place to start to get ideas: http://foodsforthesoul.net/2013/03/11/spicy-bagel-chips/, http://www.bakedbyrachel.com/2012/01/bagel-chips/
I'd like to make them from scratch. Roll out a thin baguette shaped loaf, bake it, slice with a rotary slicer, then bake to harden.
I agree Gregg, they are the best part! I also think it's the seasonings, although I don't know what they are. Great question, I hope someone in the Food52 community has a recipe for something similar.
