01 - Combine bread flour, sugar, yeast, spices, and salt in a large bowl. Mix thoroughly to distribute evenly.
02 - Add softened butter to the flour mixture and rub in with fingertips until texture resembles coarse breadcrumbs.
03 - Whisk lukewarm milk and egg together in a separate bowl until fully combined.
04 - Pour milk mixture into dry ingredients. Mix with a wooden spoon until soft, sticky dough begins to form.
05 - Turn dough onto lightly floured surface. Knead vigorously for 8–10 minutes, pushing dough away with heel of hand and folding back, until smooth, elastic, and no longer sticky.
06 - Place dough in lightly oiled bowl, turning to coat all surfaces. Cover with plastic wrap or warm damp towel. Let rise in warm, draft-free area for 1 hour until doubled in size.
07 - Punch down risen dough to release air. Turn onto floured surface and knead in dried fruit and orange zest until evenly distributed throughout dough.
08 - Divide dough into 12 equal portions. Shape each piece into smooth, tight ball by tucking edges underneath. Arrange on parchment-lined baking sheet, spacing 2 inches apart.
09 - Cover loosely with plastic wrap or clean towel. Let rise in warm place for 45 minutes until buns are puffy and have increased noticeably in size.
10 - Preheat oven to 390°F during final rise period.
11 - Mix flour with 5 tablespoons water in small bowl, adding remaining tablespoon only if needed to achieve thick, pipeable paste consistency. Transfer to piping bag or zip-top bag with corner snipped.
12 - Pipe straight vertical line down center of each bun, then pipe horizontal line across to form cross. Work quickly and gently to avoid deflating risen dough.
13 - Bake for 20–25 minutes until golden brown and internal temperature reaches 190°F. Buns should sound hollow when tapped on bottom.
14 - While buns bake, heat apricot jam with water in small saucepan over low heat, stirring until jam melts and mixture becomes smooth. Strain through fine mesh sieve if lumps remain.
15 - Immediately brush warm buns generously with apricot glaze as soon as they come out of oven. Transfer to wire rack and cool completely before serving.
