Preheat the oven to 150C/300F/gas mark 2
Use a 23cm/9 inch round cake tin.
Put all the dried fruit in a bowl, pour the apple juice concentrate over and leave to soak overnight, Stir from time to time to make sure all the fruit is soaked.
Put the margarine and sugar in a large mixing-bowl and cream well together before stirring in the molasses, flour, soya milk and mixed spice. An electric mixer may be used if you prefer. Fold in the soaked dried fruit and stir till evenly distributed through the mixture.
Line the cake tin with grease-proof paper. Pour in the mixture and bake for about 3 hours till a warm knife inserted in the centre comes out cleanly. Allow to cool on a rack before removing from tin.
