                Whisk pistachio paste with part of the heavy cream (¼ cup) in a large bowl until nice and smooth. Fold in mascarpone, almond extract, vanilla, and salt, mixing until it’s creamy.
              
              
              
                02 - 
                In another bowl, whip the remaining 1 cup of heavy cream with the sugar using beaters or a stand mixer until peaks hold their shape.
              
              
              
                03 - 
                Gradually fold the whipped cream into the pistachio mascarpone mixture with a spatula. Set it aside.
              
              
              
                04 - 
                Stir together coffee, pistachio extract, and amaretto (if you're using it) in a wide, shallow dish until it’s mixed up.

                Dip half the ladyfinger cookies quickly into coffee one at a time and line them in a single row at the bottom of a 9x9 pan. Pour half of the cream mixture on top and spread evenly.
              
              
              
                06 - 
                Repeat the dipping process with the rest of the ladyfingers. Stack them neatly above the first layer and coat with the remaining cream. Smooth out the surface.
              
              
              
                07 - 
                Drizzle some pistachio paste over the top, thinning with a splash of water if it’s hard to spread. Garnish with finely chopped pistachios. Let it sit in the fridge for at least 2 hours or leave overnight for an extra chill.
