On the day before making the cassata, prepare the homemade ricotta cheese. It's much cheaper if you make it yourself than buying it.. (^_^)v You'll be able to make 330 g of ricotta cheese using 1 liter of milk.
On the next day, take out the ricotta cheese from the refrigerator and bring it to room temperature.
Put the ume plums leftover from umeshu in a microwave-safe container and microwave for 3 minutes at 600 W. Pour in the umeshu and let it cool.
While cooling the ume plums, dice the nuts and chocolate into about 5 mm cubes.
Once the ume plums cool down, remove the seeds, dice them into 5 mm cubes, and return them into the umeshu.
The ume plums will soak up the umeshu and the moisture will reduce. This will take about 15-20 minutes.
Beat the heavy cream, add the sugar, and whisk until its stiff.
Add the ricotta cheese, combine well, mix in the nuts, chocolate, and ume plums, and pour the mixture into a pan lined with a sheet of parchment paper.
Chill it in the freezer for at least 6 hours, or if possible, leave it overnight.
Story Behind this Recipe
I was searching for a way to use my homemade mock ricotta cheese. I have experimented with a lot things with this ricotta cheese, like baking baked cheese cake, so this time I decided to chill it...
Traditionally, dried fruits soaked in rum would be used for cassata. But since I had ume plums leftover from umeshu sitting in the fridge, I tried using them instead... I love this cassata because it doesn't melt easily like ice cream.. (^_^)v
