For the gelato
Mix the plain base with Nonna Rachele Paste, the milk and the salt, then churn the mixture.
For the garnish
Using a planetary mixer, mix the invert sugar with the 500 ml of milk and the cold Custard Mix. Pour it into a pastry bag and put it in the fridge.
During the extraction process, ripple the gelato with the custard and the crumbled pastry.
