Prepare the kataifi dough. Heat a skillet over medium heat. Add the butter and spread the kataifi dough strands. Fry, stirring constantly, until golden and crispy (about 5-7 minutes). Place on a paper towel to remove excess grease and let it cool.
Melt the chocolate. Melt the chocolate in a double boiler until smooth and uniform.
Grind pistachios with honey in a blender, put them in a bowl and add kataifi.
Shape the dessert. Take a mold, pour about half of the chocolate, and put in the freezer for 30 min.
Put the pistachio mixture into the mold and pour the rest of the heated chocolate over it.
Chill. Place the chocolate in the refrigerator for 1-2 hours to set.
