01 - In a large mixing bowl, combine the bread flour, caster sugar, yeast, salt, cinnamon, allspice, and nutmeg. Stir in orange zest and currants until evenly distributed.
02 - Create a well in the center of the dry ingredients. Add the softened butter, lukewarm milk, and eggs. Mix thoroughly to form a sticky, cohesive dough.
03 - Knead the dough on a floured surface for 10 minutes, or use a stand mixer with a dough hook for 6-7 minutes, until smooth and elastic with good gluten development.
04 - Place the dough in a lightly greased bowl, cover with plastic wrap or a damp towel, and let rise in a warm place until doubled in size, approximately 1 hour.
05 - Punch down the risen dough and divide into 12 equal portions. Shape each piece into a smooth ball and arrange on a parchment-lined baking sheet, leaving slight space between each bun.
06 - Cover the baking sheet with a clean towel and let rise for 30-40 minutes, until the buns are puffy and have increased in size.
07 - Preheat the oven to 400°F.
08 - Mix the all-purpose flour and water into a thick, pipeable paste. Transfer to a piping bag or small plastic bag with the corner snipped off.
09 - Pipe a cross shape over each risen bun using the flour paste, applying steady pressure for clean lines.
10 - Bake for 20-25 minutes until golden brown and cooked through. The internal temperature should reach 190°F when fully baked.
11 - While buns are baking, gently heat the apricot jam and water in a small saucepan until melted and smooth. Strain through a fine mesh sieve to remove any fruit pieces.
12 - Brush the hot buns immediately with the warm glaze as soon as they come out of the oven. Transfer to a wire rack to cool completely.
