Add the dried fruit and chopped glace cherries to a pan, pour the juice over, stir well, and leave them to simmer on a medium heat until the liquid is absorbed.
Remove the pan from the heat, and set aside until ready to use.
Preheat the oven to 160 degrees Celsius (320 Fahrenheit).
Add the soft butter and sugar to a large mixing bowl, and use a hand mixer to cream them until you get a smooth texture.
Add the eggs one by one, mixing well after each addition.
Sift in the flour, add the ground almonds, baking powder, ground cinnamon and mixed spice plus the soaked fruit, and mix with a spatula until fully incorporated.
Butter and flour a 20 cm / 8 inch round cake tin.
Roll the marzipan using a rolling pin, and use the cake tin to cut 2 discs out of the marzipan.
Transfer half of the amount of batter to the tin making sure it's in an even layer and top it with one layer of marzipan.
Top the marzipan with the remaining batter, and bake it in the middle of the oven for 1 hour and 30 minutes or until a skewer inserted in the middle comes out clean.
Remove the cake from the oven and allow it to cool down completely.
Brush the cake with jam, arrange the second marzipan disc over, and shape 11 balls out of the remaining marpizan.
You might want to brush each marzipan ball with jam so they can stick better to the marzipan disc.
Use a blow torch to caramelise the top slightly.
