1 cup (2 sticks) unsalted butter, cut into 1/2-inch pieces, cool but not too firm
2 tablespoons cream cheese
1 large egg yolk
2 teaspoons rum (or 1 1/2 teaspoons pure vanilla extract)
1/4 teaspoon peppermint extract
3/4 cup mint jelly
1 tablespoon rum or water
1 teaspoon sugar
Confectioners’ sugar, for dusting
Combine the sugar and lime zest in a food processor fitted with the metal
blade or in a bowl with a wooden spoon. Add the salt and flour, mix to combine.
Add butter and cream cheese; mix until dough resembles coarse sand.
Add egg yolk, rum (or vanilla) and mint extract. Mix until the dough clumps
Transfer to a large mixing bowl and knead with your hands until it holds
together in a ball. Divide dough into two disks, wrap in plastic wrap and refrigerate
for 20 to 30 minutes.
Heat the oven to 350 degrees F with the oven racks in the upper and lower
Line two baking sheets with parchment paper or butter them evenly.
Working with one disk at a time, roll out the dough to 1/8-inch thickness
between sheets of lightly floured wax or parchment paper. Slide the rolled dough,
still between sheets of paper, onto a baking sheet, and chill for 10 to 20 minutes.
Remove top paper, carefully turn over and remove remaining paper.
Using a 2- to 2 1/2-inch cookie cutter, cut the dough into shapes and place
about 1 1/2 inches apart on the prepared baking sheets. Cut a hole out of the
center of half the cookies to make a window for the filling. Gather remaining
dough scraps into a ball, reroll and cut into shapes. Do this only once.
Bake, rotating the baking sheet about halfway through, until lightly golden,
10 to 15 minutes. The top cookies with the cutout centers will bake more quickly.
Let the cookies cool on a wire rack.
Combine mint jelly, rum (or water) and sugar in a small saucepan over medium
heat. Simmer for 2 to 3 minutes, cool to room temperature.
Using a small strainer or sugar shaker, dust the top halves of the cookies
(the ones with the holes in the centers) with confectioners’ sugar.
Place about 3/4 teaspoon of mint jelly onto a cookie bottom, smearing it
lightly around the whole cookie leaving a small mound in the center.
