Grind the saffron and salt in a small mortar. Add the vodka and let the mixture steep for 30 minutes.
Scald the milk in a saucepan over medium- low heat. Allow the milk to cool down to 115°F- 120°F. Once the milk has cooled, whisk together the milk, an egg, and the saffron mixture in a glass measuring cup.
In the bowl of a stand mixer fitted with a hook attachment, combine flour, sugar, and yeast. Mix on low to combine. On low, slowly pour in the milk mixture. Then bump the speed up to medium- low until fully combined. Add butter a piece at a time and beat until well combined.
Bump the speed up to medium and beat for about 7 minutes, or until smooth and elastic. The dough will be quite soft. Lightly grease a large bowl, add the dough, and turn to coat. Place plastic wrap directly on the dough. Cover the bowl in a tea towel for good measure. Let it rise in a warm, draft free location until doubled in size, about an hour.
Line a baking sheet with parchment paper and set aside.
Do NOT punch the dough down. Turn the dough out onto a lightly floured surface, use a pastry mat if you have one. Use your hands to shape the dough into a rough rectangle. Now roll the dough out to an 18x12 inch rectangle.
Spread the cardamom orange marmalade filling over the dough, leaving a ½ inch border on all sides. Now sprinkle with candied orange peel and golden raisins. Roll the dough up, starting on the long side in front of you. Transfer the dough to the baking sheet and form a ring. Pinch the ends together to seal.
Use kitchen shears to cut into the dough at a 45° angle. Do not cut all the way down through the dough, leave a ¼ inch of dough on the bottom. Repeat cuts every ½ inch around the wreath. Now pull each piece in alternating directions. Cover loosely with cling wrap and let it rise for 30 minutes. Begin preheating the oven to 350°F.
Brush the bread with an egg wash (1 egg beaten with a tsp of water). Sprinkle with sliced almonds and sparkling sugar. Bake for 40 minutes or until the internal temperature hits 190°F.
Cool on the baking sheet for 15 minutes before transferring to a cooling rack.
