Line a loaf pan with baking parchment.
Sift together flour, baking soda, cinnamon, and salt into a large bowl. Set aside.
In a small saucepan over medium-low heat, combine butter, brown sugar, and water. Heat, stirring often, until butter is melted and sugar is dissolved, about 5 minutes.
Add liquid mixture and almonds, pistachios, and cherries to the flour mixture and stir until all flour is moistened.
Scrape into prepared loaf pan and press dough down firmly. Fold, or place another piece of, parchment over the top.
Freeze loaf for several hours, until firm but pliable. (If desired, transfer dough to the refrigerator the evening prior to baking).
Preheat oven to 350°F. Line baking sheets with parchment.
Slice loaf very thin, about 1/8 of an inch, and place slices on baking sheet, leaving an inch of space between each wafer. Bake for 10-14 minutes or until golden brown. Cool completely on baking pans.
