Method
- Bring a small pot of water to a boil and add the raw pistachios. Boil for exactly 2 minutes, then drain immediately and transfer to a bowl of ice water for 30 seconds. Pinch each nut to remove the papery skins.
- Spread the blanched pistachios on a clean kitchen towel and rub gently to remove remaining skins. Transfer to a baking sheet and dry in a 200°F (93°C) oven for 10 minutes until completely dry.
- Add the dried pistachios to your food processor and process continuously for 8 to 10 minutes, scraping down the sides every 2 minutes, until smooth and flowing.
- Add the oil, powdered sugar, salt, and tahini to the processor with the pistachio butter. Process for another 60 seconds until completely incorporated and glossy. Set aside.
- Pull the thawed kataifi apart into a large bowl, separating any clumps with your fingers. Drizzle the melted butter over the strands and toss with your hands until every piece is coated.
- Spread the buttered kataifi in a thin layer on a parchment-lined baking sheet. Sprinkle the sugar and cardamom evenly over the top. Bake at 350°F (175°C) for 10 to 12 minutes, stirring halfway through, until deep golden brown. Let cool completely.
- Place two-thirds of your chopped chocolate (about 9 ounces) in a heatproof bowl over barely simmering water. Stir constantly and heat until the chocolate reaches exactly 115°F (46°C).
- Remove the bowl from heat and add the remaining chopped chocolate. Stir continuously until the temperature drops to exactly 82°F (28°C), then briefly return to the double boiler and warm to 88-90°F (31-32°C).
- Pour tempered chocolate into your molds, filling each cavity completely. Tilt and rotate to coat all surfaces, then invert over parchment paper and tap firmly to remove excess, leaving a thin shell.
- Spoon a generous layer of pistachio butter into each chocolate shell, spreading to cover the bottom and reach the edges. Press a layer of cooled, crispy knafeh into the pistachio butter, pushing gently so it adheres. Fill each mold to about 3/4 full.
- Pour tempered chocolate over the filling to cover completely, tapping the mold gently on the counter to release air bubbles. Use an offset spatula to scrape the surface flat and level.
- Refrigerate the filled molds for 20 minutes to set the chocolate, then transfer to room temperature for 10 minutes before unmolding. Flex the mold gently and invert; the bars should release with a light tap.
Notes
Store finished bars at cool room temperature (65-68°F) rather than in the refrigerator; cold storage dulls the chocolate's shine and can cause the knafeh to absorb moisture and turn soft. Bars keep well for about 5 days at room temperature in an airtight container, or up to 2 weeks refrigerated. The pistachio butter can be made up to 2 weeks ahead, and the toasted knafeh can be prepared up to 3 days ahead.
