Put all the dry ingredients into the bowl of a stand mixer and stir to combine.
1 3/4 cups whole wheat flour, 2 1/2 cups white bread flour, 2 tsp instant dried yeast, 2 tbsp granulated sugar, 1 tsp salt, 2 tsp ground cinnamon, 1/4 tsp ground cloves
Attach the mixer’s dough hook and pour in 1 1/4 cups of the water, then turn the mixer on to low speed and mix until everything forms a soft, slightly sticky dough. You may need to add a little more water for the dough to come together properly.
1 3/4 cups water
Let the mixer run for 5-8 minutes after the dough comes together, until it's smooth and elastic.
When the dough is smooth, turn the mixer off. Scrape the dough onto a lightly floured surface and press it out into as large a rectangle as you can. Measurements don't matter here, you're just making as large a surface area as you can without the dough springing back on you.

Scatter the dried fruit and nuts over two thirds of the dough. Fold the remaining third over half the fruit and nuts, then fold that over the other third so you've got a three-fold rectangle with all the add-ins inside the dough. Press everything out again and repeat the folding. Repeat this flattening and folding into thirds once or twice more to distribute all the fruit and nuts evenly.
2/3 cup dried apricots, 2/3 cup raisins, 2/3 cup walnuts
Bring the dough together into a rough ball and put it into a clean bowl. Put it, uncovered, in your steam oven and set to steam or dough proving at 86⁰F/30⁰C. Leave until it's roughly doubled in size, about 30-40 minutes depending on which yeast you used and what your starting room temperature was.
After the first prove, scrape the dough onto a lightly floured surface again and press gently into a large rectangle. Fold it into thirds by lifting the short sides of the dough into the middle (I use a cheap plastic dough scraper to help me with lifting and folding the dough over without using too much flour). You'll now have a vaguely square piece of folded dough. Turn it around so one of the open sides is facing you, then roll it tightly and evenly away from yourself to make a fat spiral shape. You can sort of poke the sides back in as you roll so you end up with a nice and neat loaf.

Put the dough, seam side down, into a 13"x4" (32x10cm) loaf pan. Wrap the whole thing loosely in a plastic bag (or put a shower cap over the top of the tin!), and put it in the fridge overnight – 8-12 hours is about right though I've gone as high as 14 hours and it was fine. After the second prove your loaf should have roughly doubled in size and the dough should spring back to shape when you gently press on the surface. If your finger leaves a big indent and the dough still seems ‘heavy’, it needs more time. If you've left it for too long, you'll find that when you poke the dough the whole lot deflates. You can still bake an overproved loaf but it won't rise as well in the oven, and will have a more crumbly texture because the gluten structure isn't as good.
Set your steam oven to Combi Steam, 400°F/200°C, 60% (high) humidity. Bake the bread for 10 minutes, then reduce the heat to 350°F/180°C and bake until the loaf is golden brown all over, about 25 minutes more. If you turn it out of the pan, the base of the loaf should sound hollow when tapped. If you've got an instant-read thermometer you can check for temperature instead of doing the tap test; it should read 200-210°F/93.5-99°C in the center of the bread.
Remove from the oven, turn out of the pan and leave to cool before cutting. It will keep, covered at room temperature, for a day or two, but is best sliced and frozen after that, ready for toasting.
