To make the buns
1. Start by mixing the yeast with a tablespoon of whole milk and a teaspoon of caster sugar in a large mixing bowl, until the yeast has completely dissolved. Leave on the side for 15 minutes until little bubbles start to appear.
2. Sieve in the flour, followed by the cinnamon, nutmeg and mixed spice. Add to this the rest of the milk, golden caster sugar and the egg, and stir well.
3. Using your hands, start binding the mixture together for 5 minutes until it forms a dough. Add the soft butter gradually, one chunk at a time, whilst kneading the dough. This should take 2 to 3 minutes and should result in a sticky dough. Knead for a further 5 minutes until you have a shiny and smooth dough.
4. Add to your dough the dried cranberries and candied orange peel and knead for 3 more minutes. Finally, cover your bowl with a clean tea towel and leave to proof in a bowl that has been lightly greased with butter, at room temperature for 1h30 minutes. The dough should have doubled in size.
5. Remove your dough from the mixing bowl, and place on a lightly floured work surface. Divide your dough into 20 pieces weighing 50g each. Roll each dough piece against the palm of your hand to create smooth round buns. Place these onto a large baking tray lined with baking paper, leaving a gap between them.
6. Proove the buns for a second time, covering the tray with a tea towel and leaving to rise at room temperature for about an hour, until they have doubled in size and the bun's sides are touching each other.
7. Whisk together the large egg and teaspoon of milk. Delicately brush the buns with that eggwash.
8. Preheat your oven to 240C/ 220C fan/ Gas 8.
