Add the fruit and 200ml of the warm water to a bowl and heat in the microwave for 2 minutes, then drain.
In a jug, mix the remaining warm water, ProZero, psyllium husk, yeast and the almond essence and leave to thicken for 10 minutes.
In a mixing bowl, rub together the butter, sugar, Fate Low Protein All-Purpose Mix, mixed spice, cinnamon, and ginger with your fingertips until you get a sandy texture.
Add the ProZero mixture and the fruit and mix until you get a smooth dough. Knead for 5-10 minutes. Cover and leave to rise in a warm place for 45 minutes.
Add all the ‘marzipan’ ingredients in a bowl and mix well for 10 minutes or until combined.
Roll the ‘marzipan’ out to a sausage shape to 15cm long and wrap with cling film. Place in the freezer for 20 minutes.
Once risen, roll out the dough mixture in a sausage shape 20cm long.
Lay the ‘marzipan’ on top of the dough and push in. Then roll so that the ‘marzipan’ is in the centre of the dough.
Preheat the oven to 200°C/180°C fan/Gas mark 6.
Place on a lined baking tray and brush with the melted butter. Bake for 35 minutes or until golden brown.
Allow to cool completely and serve.
