In a large bowl, thoroughly combine 1½ cups flour, sugar, yeast, salt, and anise seed.
In a small pan over medium heat, heat milk, water, and butter until nearly boiling.
Stir warmed liquid into dry mixture until thoroughly combined. Stir in eggs and add remaining flour, a little at a time, as needed, until dough is soft and not sticky.
Turn dough onto a floured surface and knead for 10 minutes. Place dough in a lightly greased bowl and cover with plastic wrap. Allow dough to rise for about 1½ hours, or until doubled in size.
Punch dough down and shape into a large round loaf. You can add sculpted dough pieces (traditionally bones or a skull) to the top, if desired. Place formed dough onto a baking sheet and cover loosely with plastic wrap. Allow to rise for an additional hour.
Heat oven to 350°. Bake bread until golden brown, 30–40 minutes. Remove from oven, let cool slightly, then brush with glaze (see below). Sprinkle glazed bread with sugar, which can be colored, and/or sprinkled into a design, if desired.
To make the glaze: Mix together ½ cup sugar, 1/3 cup fresh orange juice, and 2 tablespoons orange zest in a small sauce pan. Boil for 2 minutes.
