How to Make It
In a medium saucepan, combine the honey with the granulated sugar, lemon zest, cinnamon, black pepper, nutmeg, ginger, cloves and white pepper. Cook over low heat, stirring occasionally, until the honey and sugar are melted, about 3 minutes. Remove the pan from the heat and add the candied citrus rind, 1 cup plus 2 tablespoons of the almonds and 3 tablespoons plus 1 teaspoon of the kirsch. Sift the 2 cups plus 2 tablespoons of flour and the baking soda over the mixture and stir to incorporate. Line a baking sheet with plastic wrap. Scrape the dough onto the plastic and flatten into a disk. Wrap and refrigerate until firm, about 2 hours.
Liberally flour a work surface. Roll out the dough to a 12-inch square about 3/8 inch thick. Line a large cookie sheet with parchment paper and slide the dough onto it. Prick all over with a fork. Scatter the remaining 1/4 cup of almonds on top. Cover with plastic wrap and refrigerate overnight.
Preheat the oven to 400°. In a small bowl, mix the confectioners' sugar with the water and the remaining 2 teaspoons of kirsch. Bake the cookie square for 14 minutes, or until golden. Immediately brush the glaze on top. Slide the parchment onto a rack and let the cookie cool completely. On a work surface, using a large, sharp knife, trim the edges of the square, then cut it into four 3-inch-wide strips. Cut each strip into 3/4-inch bars.
Leckerli is a Swiss cookie that is traditionally pressed into special wooden molds to imprint designs on the surface of the cookie.
To dice the candied citrus rind easily for this cookie, occasionally spray or rub neutral cooking oil, like vegetable oil, on the blade of your knife to prevent the rinds from sticking. This trick also works well for dried fruit.
