I just invented these.
First, rehydrate 1/4 cup each dried blueberries and cranberries in some rum or brandy.
Cream together 1 stick of butter and 3/4 cup sugar. Add cinnamon, allspice, and vanilla extract to taste, plus a pinch of salt. Beat in 1 egg. Mix in the dried fruit (drink the liquor), 1/4 cup nuts (pecans or walnuts), 1/4 cup crystalized ginger (bakers cut or chopped very small). Sift in 1 and 3/4 cup flour and 1/2 t baking powder.
Form the dough into a log, wrapped in wax paper, and refrigerate for a few hours. When you're ready, heat your oven to 350°F and grease a cookie sheet (or line with parchment). Slice the log into 1/2" slices, and place 2 inches apart on the sheet. Bake for 10-12 minutes.
I think these would be nice at a solstice feast.
