Method:
Prepare the Brioche Dough:
In a mixing bowl, combine the flour, sugar, and yeast.
Add the lukewarm milk, eggs, honey, rum (if using), and lemon zest. Mix until a shaggy dough forms.
Incorporate the softened butter and a pinch of salt. Knead the dough until smooth and elastic, about 10 minutes by hand or 5 minutes using a stand mixer with a dough hook.
Shape the dough into a ball, place it in a lightly greased bowl, cover with a damp cloth, and let it rise in a warm place until doubled in size, approximately 1 to 1.5 hours.
Assemble the Kranz:
On a lightly floured surface, roll out the brioche dough into a rectangle about 1 cm thick.
Lay the puff pastry sheet over the rolled-out brioche dough, aligning the edges.
Spread a thin layer of jam over the puff pastry, leaving a 1 cm border around the edges.
Sprinkle the mixed dried fruits evenly over the jam layer.
Starting from the longer side, roll the layered dough tightly into a log.
Using a sharp knife, slice the log lengthwise down the center to expose the layers.
Twist the two halves together, keeping the cut sides facing up, to form a braid.
Shape the braided dough into a ring and place it on a baking sheet lined with parchment paper.
Final Proofing and Baking:
Cover the shaped dough with a damp cloth and let it rise for another 30 minutes.
Preheat the oven to 180°C (350°F).
Brush the top of the dough with the beaten egg to achieve a golden crust.
Bake in the preheated oven for 25 minutes or until golden brown.
Cooling and Serving:
Remove the Kranz from the oven and allow it to cool on a wire rack.
Once cooled, slice and serve.
Variations and Tips:
Nut-Free Option: Replace dried fruits with chocolate chips for a different flavor profile.
Gluten-Free Version: Substitute with a gluten-free flour blend suitable for brioche recipes and ensure the puff pastry is also gluten-free.
Dairy-Free Adaptation: Use plant-based butter and milk alternatives to accommodate dairy restrictions.
Flavor Enhancements: Consider adding a sprinkle of cinnamon or nutmeg to the filling for a warm spice note.
