Any holiday-motif cookie cutter can be used to make these. Beat in yolk, lemon peel and vanilla extract. Add flour and salt and beat until mixture begins to clump together. Divide dough into 3 equal pieces. Position 1 rack in center and 1 rack in top third of oven and preheat to 375 degrees F. Line 2 large baking sheets with parchment paper.
Transfer cookies to prepared baking sheets.
Carefully spoon ground candies into cookie cutouts, filling cutouts completely to same thickness as cookies. Sprinkle cookies lightly with additional sugar. Using straw, cut out hole in top of each cookie. Repeat with remaining dough disks, ground candies and additional sugar. Reroll dough scraps and cut out additional cookies.
