How to Make It
Heat oven to 350° F.
Cut the dough crosswise into 2 portions; refrigerate 1 portion. Roll the other one on a floured surface to ⅛ inch thick. Using a small (preferably 2-inch) star-shaped cookie cutter, cut the dough into cookies. Repeat with the remaining dough.
Bake until golden around the edges, 10 to 12 minutes. Transfer to a wire rack to cool. Repeat with the remaining dough, rerolling the scraps.
Turn half the cookies upside down and spread with about ½ teaspoon of jam each. Sandwich with the remaining cookies.
