In a small pan, heat the milk with the butter until the butter has melted and the mix begins to steam.
Once it begins to steam, immediately take this off of the heat and place to one side.
In the meantime mix the flour, yeast, sugar and spices in a large bowl and place to one side.
Check that the milk and butter is still warm to the touch and pour into the bowl of dry ingredients and bring together into a ball of dough with your hands.
Turn the ball of dough out on to a lightly floured surface and knead for 10 minutes or until the ball is smooth and elastic.
Place the dough back into the bowl and cover with cling film or a tea towel to prove in a warm place for roughly 1 hour or until the dough has roughly doubled in size.
After the initial prove, stretch the dough out until flat.
Cover the dough with ⅔rds of the mixed peel and the banana.
Knead the dough for roughly 5 minutes to incorporate the layers of fruit into the dough. The banana will have made it sticky.
Line a large oven dish with grease proof paper.
Cut the dough into 8 equal sized pieces and roll into smooth balls.
Place the 8 balls into the oven dish allowing room for them to grow and spread.
Again, cover with either cling film or a tea towel and leave in a warm place to prove for a further 30-45 minutes.
Once the dough has increased in size again, pre-heat your oven to gas mark 5 / 180C.
Before baking, make a paste with the plain flour and water. It should be stiff enough to pipe
Add the paste into a piping bag and pipe crosses on top of the buns.
Bake in the oven for 20-25 minutes until golden brown.
Just before the 20 minutes is up, mix the maple syrup and hot water together.
Take the buns out of the oven when the 20-25 minutes is complete and brush the buns with the maple glaze.
Allow to cool on a wire rack before eating.
