Place the flour, psyllium husk powder and mixed spice into a large bowl or stand mixer and stir well.
Mix the milk kefir and honey together, then add to the dry mixture. Stir well until you have a dough, using your hands to bring it together if you need to
OPTIONAL STEP (not necessary but develops flavour) - Cover with a tea towel and leave to stand at room temperature for about 24 hours
After the proving time is up, mix the baking powder into the oil along with the vanilla extract and pour over the dough
Beat the eggs and add them to the dough too, then give it a stir to combine the wet ingredients into the dough. Go slowly and carefully at first, then once combined give it a good beat
Add the mixed fruit and mix well
Grease a 2lb loaf tin ( I recommend this one for best results) then add the dough and level. With wet fingers smooth the top neatly
Place a wet tea towel over the loaf and put in a warm place for 1 hour, to rise. I place a cup of boiling water in the oven with the loaf to aid the rising process.
After the hour, cook the loaf in a pre-heated oven (I just take my loaf out while I pre-heat the oven) at 220 degrees (200 fan, gas mark 7) for 10 minutes, then reduce the temperature to 180 degrees (160 degree fan, gas mark 4) for a further 40 minutes or so until golden.
Leave to cool completely.
If you wish to drizzle icing on it, mix the icing ingredients together, decorate and enjoy. Alternatively brush the top of the loaf with runny honey for a shiny glaze.
