1. Mix the flour, sugar, yeast, and salt together in a large bowl. Add the butter and rub it in with your fingertips. Make a well in the center. Pour in the milk and egg and mix to form a soft dough. Knead on a lightly floured work surface for 8 minutes, or until smooth and elastic. Shape into a ball. Place in a lightly oiled bowl and turn to coat the dough. Cover tightly with plastic wrap. Let stand in a warm place about 1 hour, until doubled.

2. Lightly butter the cake pan. Knead the dough on a lightly floured surface and roll into a rectangle about 12 × 9in (30 × 23cm).

3. To make the filling, brush the surface of the dough with the melted butter, leaving a 1in (2.5cm) border along the long sides. Mix the raisins, brown sugar, and spice together and sprinkle over the butter. Starting at a long side, roll up the dough and pinch the seam closed. Slice the dough into 9 equal pieces. Arrange the slices in the pan. Cover loosely with plastic wrap and let stand about 30 minutes, until doubled.

4. Preheat the oven to 375°F (190°C). Bake for 30 minutes, until golden brown. Transfer to a wire rack. Brush the buns with the honey. Let cool for about 10 minutes, then remove from the pan and serve warm.
