In a bowl mix together flour, sugar, mixed spice, cinnamon, lemon zest, salt and yeast, set aside.
In a small pot over medium-high heat, melt butter and milk, allow to cool to hand warm.
Make a well in the centre of the flour and pour in milk and butter mixture, add the egg.
Using your hand, pull in the flour and mix to get a sticky dough.
Pour dough onto a lightly floured surface and knead for 5-10 minutes until dough is soft, smooth and elastic. An electric mixer with a dough hook can be used.
Knead in the mixed fruits.
Lightly grease a bowl and place dough inside, cover with a tea towel or cling film and leave in a warm place to rise until double in size, about 1 hour.
Divide dough into 24 balls, and roll each ball lightly to form a ball.
Place balls on a baking tray close together but not touching, flatten slightly.
Loosely cover with cling film or tea towel, it should not touch the buns and place in a warm place to rise until double in size about 1 hour.
When poked with a finger, the dough should leave a dent that slowly rises but if it feels firm or dense and does not leave a shallow dent, leave it to prove for another 10-20 minutes more.
Preheat oven to 200 deg. C.
