In a large mixing bowl, blend together the pistachio paste and a quarter of the heavy cream using a whisk or hand mixer until it's fully smooth. Then, add in mascarpone, vanilla, almond essence, and salt. Whisk until creamy and lump-free.

Use a stand mixer with a whisk head, or hand beaters in another bowl, to whip the last 1 cup heavy whipping cream and sugar until stiff peaks develop.

Take the whipped cream and gently fold it into the mascarpone mixture with a spatula until blended. Keep it aside.

Quickly dip half the ladyfingers one by one into the coffee mixture. Lay each on the bottom of a 9x9-inch pan, forming a single layer. Cover this layer with half the cream mixture, spreading it out evenly.

Use the rest of the ladyfingers, dipping each one into the coffee again, and arrange them to make another full layer. Spread the remaining cream mixture on top, making sure the surface is smooth.
