20 minutes before you begin baking, combine the freeze dried fruit with warm water and set it aside to rehydrate. Once the fruit is rehydrated, strain it in a colander and allow the excess liquid to drain while you make the dough.
Preheat oven to 325°F. Line baking sheets with parchment paper or a silicone baking mat.
Using a hand mixer or stand mixer, cream together the butter and sugar in a large bowl until light and fluffy (about 4 minutes).
Add the egg and mix again until well combined.
In a different bowl, whisk together the dry ingredients (flour, salt, baking soda, cinnamon, nutmeg, and allspice or cloves).
Add half of the dry ingredients to the butter and sugar mixture. Combine until incorporated.
Mix in buttermilk, rum, and vanilla flavoring until distributed evenly.
Add remaining dry ingredients and mix until smooth.
Using a flexible spatula, fold the fruit and nuts into the cookie dough to distribute evenly.
Using a tablespoon or small cookie scoop, drop dough onto the prepared baking sheets, spacing them about 2 inches apart.
Bake for 12-15 minutes, until lightly golden brown.
Allow cookies to cool on the baking sheet for 3 minutes, then move to a rack to cool completely.
