Preheat oven to 375 degrees F. Lightly butter an approximate 12" x 17" x 1" baking pan.
In a large bowl, combine flour, salt, baking soda, cloves, cinnamon, almonds, candied citron, and candied orange peel; set aside.
In the top of a double boiler over hot water, combine honey, sugar, and whiskey; stir until sugar is dissolved.
Remove from heat and let mixture cool a little. Add eggs, a little at a time, beating well after each addition; add to flour mixture and mix until well blended.
Spread batter onto the prepared baking pan.
Bake 18 to 20 minutes or until toothpick inserted in center comes out clean and they are light brown.
Remove from oven and place on a
wire cooling rack.
While bars are baking, prepare Milk Frosting.
While the Lebkuchen is still hot, spread the Milk Frosting onto the top of the baked Lebkuchen with a spatula or a
pastry brush. Let cool, cut into bars, and remove from pan.
Store, tightly covered, at room temperature to let mellow. These cookies get even better with age (if you can wait to eat them).
Yields 5 dozen squares.
