Brew some rich coffee, then pour it into a shallow dish. Blend in rum (if you're using it) and almond extract. Give it a stir and put aside.

Separate the egg whites into the stand mixer bowl and pop the yolks in another one. Beat the whites with the whisk while slowly sprinkling in half the sugar. Keep this going on high speed till stiff peaks form—it'll take around 3 minutes. Move the whites into a big bowl, using your rubber spatula to scrape it clean.

Dump the yolks into the mixer with the rest of the sugar. Whisk on high until it's pale yellow and fluffy (roughly 3 minutes). Toss in mascarpone, then add the pistachio paste, almond extract, and vanilla. Combine well.

Spoon half the yolk mixture into the whipped whites. Gently fold them together. Add the second half and fold again until everything's evenly mixed, but don't go overboard or the whites will flatten.

Swiftly dip both sides of each lady finger into the coffee mix (too long will make them mushy). Line them up in the bottom of a 9 x 9-inch pan. Spread half of the mascarpone mix over the top. Repeat with another coffee-dipped lady finger layer, topped by the remaining mascarpone.

Scatter those finely chopped pistachios across the surface. Pop it in the fridge for a minimum of 4 hours—overnight chilling works even better. When it's ready, dig in!
