*If using fresh yeast, add it to the finger-warm milk and mix until dissolved. Then pour it into the bowl of a food mixer fitted with a dough hook attachment.
If using dried yeast, sprinkle the yeast granules into the finger-warm milk and whisk together. Cover with cling film and leave in a warm place for about 15 minutes to activate and become frothy and bubbly. Pour into the bowl of a food mixer with a dough hook and stir in the melted butter. Add the sugar and stir again. Add half of the flour as well as the salt, baking powder and ground cardamom. Add half the beaten egg (reserve the other half for brushing before baking).
