Preheat the oven to 175 °C - 350° F.
Mix clarified butter and vegetable oil in a small bowl.
Open the packaging of phyllo dough, lay it on a clean worktop, and keep it covered with a damp towel to prevent it from drying out.
Place one sheet of phyllo dough on a clean working surface and drizzle a spoon of the butter mixture over it. Place another phyllo sheet on top and lightly drizzle it with butter too.
Sprinkle on 2 tablespoons of ground pistachio over half of the buttered phyllo sheets, and spread it evenly.
Place oklava (thin rolling pin) at the bottom of phyllo sheet as it shows in the picture, and roll it up.
Using your hands, gently press the ends towards the middle, tuck them in and remove the rolling pin. Place it on your baking dish and repeat with the remaining phyllo sheets.
Using a sharp knife, cut the each of the baklava rolls in three pieces. 16 pieces of phyllo sheets will give you 24 portions in total.
