This recipe crafts traditional German Lebkuchen, featuring a fragrant, spiced dough enriched with finely ground toasted hazelnuts and almonds, brightened by generous citrus zest. Baked into soft, aromatic cookies, they are finished with a simple confectioners' sugar glaze, perfect for holiday indulgence or a comforting snack.
For authentic Lebkuchen, ensure hazelnuts and almonds are toasted thoroughly and cooled before grinding; this deepens their flavor significantly. Grind nuts with the granulated sugar to prevent them from turning into paste. When zesting citrus, use a microplane and extract only the colored zest, avoiding the bitter white pith. Do not overmix the dough once flour is incorporated, as this can develop gluten and lead to tough cookies. The dough will be soft; chilling can help with handling, though Lebkuchen is often dropped or spread. Allow cookies to cool completely before glazing to prevent the glaze from melting. For best results, allow the glazed Lebkuchen to rest for a day or two in an airtight container; the flavors meld and the texture softens beautifully, characteristic of traditional German Lebkuchen.
