Proof the yeast by combining the warm milk, active dry yeast, tablespoon of sugar, and 2 tablespoons of flour together in a small bowl. Whisk and set aside for 10 minutes until the mixture is foamy on the surface.
½ cup Milk, 1 tablespoon Active dry yeast, 1 teaspoon Sugar, 2 tablespoon Bread flour
In large mixing bowl, combine the flour, sugar, ground Mahleb (or almond extract), Mastic (or cardamom), salt, and orange zest together. Mix well to combine.
5½ cup Bread flour, 1 cup Sugar, 1 tablespoon Ground Mahleb, ½ teaspoon Ground Mastic, 1 teaspoon Salt, 1 tablespoon Orange zest
Add proofed yeast mixture and the remaining warm milk, beaten eggs, and vanilla to the large mixing bowl with the flour mixture, and mix until combined. Add the softened butter and mix again for 2 minutes until butter combined.
½ cup Milk, 3 large Eggs, 1 teaspoon Vanilla, ½ cup Butter
Turn out on a lightly floured surface and knead for 8 to 10 minutes, or till the dough surface is satiny. PRO TIP: Use a stand mixer with a dough hook, or electric kneading mixer, and eliminate hand kneading Allow 8-10 minutes for stand mixer kneading. Form a ball and set in a large, oiled bowl. Turn the dough so that it's covered in oil all over. Cover with plastic wrap and set aside in a warm place until doubled in volume. About 1 and ½ to 2 hours.
Punch the dough down and divide into three equal portions on a parchment paper covered large baking sheet.
Roll each portion into about 20 inch long ropes. Pinch the ends of the three ropes on one end and braid, curving to form a circle. Join the two ends by weaving the loose ends into the braided start point, pinching to secure. Gently tuck the dried, red dyed eggs into the braiding, spaced equally apart.
Cover the braided wreath with a lightweight cloth and set in a location to rise for 30-40 minutes. The dough will rise up around the three eggs, securing them better. Preheat the oven to 350 °F while the braid is rising.
To make the egg wash, mix the egg with the water and gently brush the surface of the braid, avoiding the eggs. Sprinkle the surface with sliced almonds.
1 Egg, 2 tablespoon Water
Bake in the center rack of the oven for 35-40 minutes, or golden brown, taking care not to over bake. Remove from the oven and cool at least 30 minutes before serving.
