Grind the buckwheat or oats in a food processor fitted with an S blade till coarsely ground. Add the salt, cinnamon, and flax and grind till very finely ground.

Add the carrot and dates and pulse to combine. Keep processing till mixture is smooth. Add water as needed, till the mixture is mushy and even but not "wet" (you should be able to shape it into small, firm cookies that will hold their shape).

Pulse in the walnuts and raisins.

To dehydrate: Place cookies on mesh-lined dehydrator sheets and dehydrate at 115 for four hours or so. Flip them over, and continue dehydrating for another four hours, or until firm but not dried through.

To bake: Preheat oven to 350. Place cookies on a parchment lined baking sheet and bake for fifteen minutes. Flip the cookies over and continue baking for another ten minutes. Let cool before enjoying!

Makes about 25 cookies.
