In a large bowl, whisk the double cream and icing sugar until soft peaks form. Gently fold in the mascarpone and pistachio paste until just combined, being careful not to overmix.

Pour the strong coffee into a shallow dish. Quickly dip each sponge finger into the coffee for just a couple of seconds per side - they should absorb some flavor but still remain firm to the touch.

Arrange a layer of coffee-soaked sponge fingers across the base of your serving dish. Carefully spread a portion of the pistachio cream mixture over the sponge finger layer.

Continue alternating layers of soaked sponge fingers and pistachio cream until all ingredients are used, making sure to finish with a cream layer on top. The number of layers will depend on the size and shape of your dish.

Pipe lines of pistachio paste across the top, then use a toothpick to drag through the lines in the opposite direction, creating an elegant feathered pattern. Cover and refrigerate for at least 6 hours or ideally overnight.

Remove from the refrigerator about 20 minutes before serving. Sprinkle with chopped pistachios just before bringing to the table.
