Begin by pouring the Marsala and orange juice into a small saucepan and heating gently.
Then add the dried fruits, and remove the pan from the heat to allow them to steep in the juice for half an hour until they have swelled slightly. Then drain them in a sieve set over a bowl to catch the liquid and leave to get cold.
Meanwhile, in a large bowl put the ricotta cheese, crème fraîche, chocolate drops, orange zest, chopped pistachios and sugar, give everything a good stir, then add the drained fruit when it is cold.
Now line the base and long sides of the loaf tin with the sponge fingers, dipped first in the reserved Marsala and orange juice and trimmed to fit comfortably.
They need to be put in sugar-side down. Reserve 6 to 8 soaked sponge fingers for the top. After that, any remaining liquid can be sprinkled over the biscuits in the tin. Next, spoon in the ricotta and fruit mixture, patting it down into the tin to remove any air bubbles.
Finally, place the remaining soaked biscuits on top. Cover tightly with clingfilm and refrigerate overnight.
Next day, serve cut into thin slices – it doesn’t need any accompaniment as it’s really yummy as it is.
