Honey Cake Parfait Slices
For the parfait, cut dark crusts from honey cakes. Grate honey cakes to fine crumbs and set some aside for garnish. Cook sugar and water until syrupy, about 3 minutes. Beat egg yolks until frothy. Pour sugar syrup in a thin stream into egg yolks and continue beating until light and creamy, about 8 minutes. Beat cream until slightly stiff and fold into parfait mixture with honey cake crumbs, gingerbread spices and 2 tablespoons rum. Spread parfait mixture into a loaf pan about 1 liter capacity (approximately 4 cup capacity) and freeze for 5-6 hours.
For the sauce, stir orange juice into lingonberries in a saucepan and bring to a boil. Mix cornstarch with a little cold water and stir into lingonberries to thicken. Stir remaining rum into lingonberry mixture, let cool and drizzle onto serving plates. Cut parfait into slices, serve on prepared plates and sprinkle with honey cake crumbs.
