Place the wholemeal bread and rye flours, sugar, salt, yeast, mixed spice and cinnamon into a large bowl. Stir them together then make a well in the centre of these dry ingredients. Pour the paste mixture into the well then stir everything together to make a dough.
Tip the dough onto a work surface dusted with flour and knead for 6 to 8 minutes until smooth and slightly sticky, adding flour as needed.
Place the dough back into the bowl and cover it with clingfilm. Leave it in a warm place for 2 hours or in the fridge for 12 hours. The dough should have doubled in size***.
After this resting period, add the orange zest and raisins to the bowl – fold and knead them into the dough.
Divide the dough into 8 pieces and roll them into balls.
Grease a 2lb loaf tin with some rapeseed oil and line the balls of dough up in the tin (2 rows of 4 dough balls). Cover the tin loosely with oiled clingfilm and leave in a warm place for around 45 minutes to rise again.
Remove the clingfilm from the dough. Mix together the cross mixture (adding enough water to make a pipeable paste) and place into a sandwich bag with the very corner cut off. Pipe it in continuous lines across/along the rows of the dough, decorating each ball with a cross.
Bake for 30-40 minutes in an oven preheated to 180 C until deep golden on top.
Meanwhile heat the glaze ingredients in a small saucepan over a medium heat. Stir and bring to the boil, cooking it until reduced by half. Remove from the heat.
Remove the baked bread from the tin and brush all over with the warm glaze. Leave to cool completely before slicing. The glazing of the loaf is completely optional but it helps add a bit of extra sweetness and makes it look even more amazing!
