Ingredients

1/2 cup dark rum 

1 cup dried currants 

2 sticks (16 tablespoons) unsalted butter, room temperature 

3/4 cup confectioners' sugar 

1/2 teaspoon finely grated orange zest 

1 teaspoon pure vanilla extract 

1 1/2 cups all-purpose flour 

3/4 cup finely shredded unsweetened coconut 

1 teaspoon coarse salt 

Preparation

Combine rum and currants; cover, and let stand at room temperature overnight. Drain, reserving 2 tablespoons rum.

Beat butter, sugar, and orange zest with a mixer on medium speed until creamy and smooth, about 2 minutes. Add vanilla and reserved rum, and beat until combined. Reduce speed to low. Add flour, coconut, and salt, and beat for 3 minutes. Stir in currants by hand.

Form dough into 2 logs, each about 1 1/2 inches in diameter; wrap in parchment, and refrigerate 1 hour (or up to 3 days).

Preheat oven to 325 degrees. Remove parchment. Slice logs into 1/4-inch-thick rounds, and space about 1 inch apart on baking sheets lined with parchment. Bake until pale golden, about 20 minutes. Let cool.
