Using a large pot, heat molasses, honey, sugar and brandy and boil for 5 minutes. Take off heat and while hot stir in butter and four cups of flour, the spices, chopped nuts and citron. Wait until cooled almost completely and add the baking soda (dissolved in a little water). Add the well-beaten eggs and enough flour to make a stiff dough (add more flour if needed). Put in an earthen or wooden bowl and let stand at room temperature 3–4 days.
When ready to bake, preheat oven to 350°.
Roll out the dough and cut out cookies (use any shape you like). Place the cookies on a baking sheet covered with parchment or Silpat. Bake in the preheated oven for about 8 minutes.
Brush with honey when they’re still hot. Let cool completely.
