Preheat oven to 300°F. Lightly oil a 13 x 18-inch (or similar size) baking sheet.
Place the buckwheat in a strainer and rinse and drain thoroughly.
In a bowl, combine the wet buckwheat, almonds, sugar, cinnamon, cardamom and salt. Spread evenly on the baking sheet.
Bake at 300°F for 20 minutes, then stir. Bake for an additional 15 - 20 minutes or until lightly browned.
After removing from the oven (while the cereal is still hot) place it in a large mixing bowl and thoroughly stir in the nut butter, then mix in the dried fruit and let cool to crisp up.
