01 - In a large mixing bowl, combine bread flour, sugar, yeast, cinnamon, allspice, nutmeg, and salt.
02 - Add softened butter, egg, and lukewarm milk. Mix until a shaggy dough forms.
03 - Knead by hand or with a stand mixer for 8–10 minutes, until smooth and elastic.
04 - Add currants and orange zest, knead gently to distribute evenly throughout the dough.
05 - Place dough in a lightly oiled bowl, cover, and let rise in a warm place until doubled in size, about 1 hour.
06 - Punch down the dough and divide into 12 equal pieces. Shape each into a ball and arrange on a parchment-lined baking tray, spacing slightly apart.
07 - Cover and let rise for 45–60 minutes, until puffy and nearly doubled in volume.
08 - Preheat oven to 350°F.
09 - Mix flour and water to a thick paste. Transfer to a piping bag and pipe a cross over each bun.
10 - Bake for 20–25 minutes, until buns are golden brown and sound hollow when tapped.
11 - While buns bake, heat apricot jam and water together until melted.
12 - Brush warm glaze over buns immediately after baking.
13 - Cool on a wire rack before serving fresh or toasted with butter.
