In a large mixing bowl, whisk together the flour, salt, and spices.
In a separate bowl, stir together the water, yeast, and a couple of tablespoons of flour. Allow it to sit for about 10 minutes until bubbly.
Add the yeast mixture, olive oil, cognac, orange juice, and zest to the dry mixture. Stir until everything is well combined.
Add nuts, cloves, and raisins if you like them. Save some dough to decorate the final bun.
Transfer the dough to a floured surface and knead for about 10 minutes until it is smooth and elastic.
First rise: Place the dough in a greased bowl, cover it with a towel, and let it rise for 1 hour in a warm place.
After the first rise, press the dough to release air. Shape it into a round disk and place it in a round pan. Cover again and let rest at warm temperature.
While the bread rests, roll the extra dough into strips to create the cross and add full nuts at each end of the cross.
Before baking, brush the top of your bread with a beaten egg and set the cross on the top.
Bake in a preheated oven at 200°C for 25 to 30 minutes. Then, lower the temperature to 170°C and continue baking for an additional 10 minutes.
