Put the dried fruit in a little bowl and completely cover it in water (or in rum or brandy or in cold tea if you would like a grown-up hot cross bun). Let this sit while you prepare your pre dough.
Measure the flours in a big mixing bowl and blend them together. Make a big well in the flour. Sprinkle in the yeast and the sugar. Pour over 280 g of the the milk that you have heated up and cooled down. Flick a layer of flour over the milk to close the well and leave it for one hour.
Add the egg, salt, and spices and knead well for 10 minutes. The mixture will be sticky but don’t let that stop you. Use a scraper and use it to gather all the dough up as you knead. Add the butter and knead it in for another 10 minutes. It won't get less sticky! You can do all the kneading in a machine on the lowest speed.
Pop it back in the bowl, cover it with a tea towel and let it rest for 20 minutes.
Drain the fruit, reserving the liquid, and incorporate the fruit into the dough gently with your hands. Don't worry about the dough - it will recover. Just don't squish the fruit or you get brown smeary bits in the dough!
Pop the dough back into the bowl, cover it and let it rest for 2 hours, until it has doubled in size.
When the dough has risen, scrape it out onto onto the counter. Don’t put any flour down as you will need a sticky surface to shape the buns.
