Separate the eggs, first beat the 6 whites with 2 tablespoons of sugar until stiff peaks form.
Then, in a separate bowl, whisk the 6 egg yolks with 4 tablespoons of sugar and 2 packets of vanilla sugar until fluffy. Then add the mascarpone, pistachio cream and rum flavouring and mix.
Then mix the contents of the 2 pans gently by hand to minimize the foam breaking.
Prepare the latte, I also add a little rum or rum flavouring.
Dip the baby biscuits in the milky coffee and lay out a whole row (don't soak them for too long, as they will soak up quickly, just for a moment.)
Then half the mascarpone cream and sprinkle with crushed pistachios.
Next layer of dipped baby sponge, then the other half of the cream and top with crushed pistachios.
I layer it in an airtight container, put the top of the container on top and put it in the fridge, it will be perfectly soft the next day.
