Instructions:
Prepare the Biga (Starter):
In a bowl, mix together the flour, water, and instant yeast until a shaggy dough forms.
Cover and let it rise at room temperature for 12-16 hours, or overnight.
Mix the Dough:
In a large bowl, combine the biga with the flour, salt, instant yeast, sugar, butter, eggs, egg yolk, Fiori di Sicilia (or vanilla and orange oil), and orange zest.
Mix until a sticky dough forms.
Add the dried fruit and mix until evenly distributed.
First Rise:
Cover the bowl and let the dough rise in a warm place until doubled in size, about 1-2 hours.
Shape the Dough:
Gently deflate the dough and transfer it to a lightly floured surface.
Shape it into a loaf or place it into a dove-shaped mold.
Second Rise:
Cover and let the dough rise again until doubled in size, about 1-2 hours.
Prepare the Topping:
Preheat the oven to 350°F (175°C).
In a small bowl, whisk the reserved egg white until frothy.
In another bowl, mix the almond flour, sugar, and sliced almonds.
Bake:
Brush the risen dough with the egg white.
Sprinkle the almond mixture evenly over the top.
Bake for 30-35 minutes, or until the bread is golden brown and a toothpick inserted into the center comes out clean.
Cool:
Allow the bread to cool completely on a wire rack before slicing.
Variations and Tips:
Chocolate Chip Colomba: Add 1 cup of dark chocolate chips to the dough for a rich, chocolaty twist.
Whole-Wheat Flour: Substitute half of the all-purpose flour with whole-wheat flour for a nuttier flavor.
Dried Fruit Mix: Incorporate a mix of dried fruits like raisins, currants, and candied citrus peel for added complexity.
Dairy-Free Option: Replace butter with a non-dairy alternative like coconut oil.
