Method:
Prepare the Raisins:
Soak the raisins in warm water for about 10 minutes to plump them up. Drain and set aside.
Mix the Dough:
In a large mixing bowl, combine the flour and sugar.
Dissolve the yeast in half of the warm water. Pour this mixture into the flour and sugar, and begin mixing on low speed using a dough hook. Gradually add the remaining water until the dough starts to come together.
Incorporate Egg and Butter:
Add the egg yolk and softened butter to the dough. Continue kneading on low speed until the dough becomes smooth yet slightly sticky.
Add Flavorings:
Gently fold in the anise seeds, drained raisins, and salt. Mix until evenly distributed throughout the dough.
First Proofing:
With oiled hands, shape the dough into a ball and place it in a lightly greased bowl. Cover with a damp cloth and let it rise in a warm place for about 3 hours, or until doubled in size.
Shape the Loaf:
Transfer the risen dough to a greased surface. Gently deflate it and roll it into a long rope.
Line a baking sheet with parchment paper. Place a small cup or bowl in the center and wrap the dough around it to form a ring, sealing the ends together.
Make several cuts around the top of the dough to facilitate even rising.
Second Proofing:
Cover the shaped dough and let it rest for at least 1 hour.
Prepare the Glaze:
In a small bowl, combine the egg white, water, and sugar. Whisk until frothy.
Bake:
Preheat the oven to 180°C (350°F).
Brush the dough with the prepared glaze.
Bake for about 45 minutes, or until the bread is golden brown.
Allow the buccellato to cool completely on a wire rack before slicing.
Variations and Tips:
Dried Fruits: Substitute raisins with dried cranberries or chopped dried figs for a different flavor profile.
Spices: Add a teaspoon of ground cinnamon or nutmeg to the dough for a warm spice note.
Nuts: Incorporate chopped almonds or walnuts for added texture.
Dietary Substitutions:
Vegan: Replace the egg yolk with a flaxseed egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) and use a plant-based butter alternative.
Gluten-Free: Use a gluten-free all-purpose flour blend suitable for yeast breads.
