Ruby Raspberry Pistachio Crunch Bars Step-by-step instructions

Before you start

Before starting, gather all ingredients and equipment. Ensure the kataifi is at room temperature, and have the ganache and pistachio cream ready. Chop the ruby chocolate into small, even pieces for even melting. Set up a double boiler or a heatproof bowl over a saucepan of simmering water.

Have the bar molds clean and dry. If using a thermometer, calibrate it to ensure accurate readings. Prepare a clean work surface for unmolding the bars later. This recipe moves quickly once you start, so having everything within reach is essential.

Instructions

Phase 1: Toasted Kataifi & Filling

1. 1Toast the Kataifi
   In a large skillet over medium heat, melt the butter. Add the shredded kataifi and cook, stirring constantly, until golden brown and crisp, about 5 minutes. Transfer to a bowl and let cool for 5 minutes.
   Look for The kataifi should be deeply golden and smell nutty; it will crisp further as it cools.
   Tip Keep stirring to prevent burning; the shreds are thin and can go from golden to burnt quickly.
2. 2Make the Filling
   In a mixing bowl, combine the toasted kataifi, white chocolate raspberry ganache, and pistachio cream. Fold gently until everything is evenly coated.
   Look for The mixture should hold together when pressed but not be overly wet.
   Tip Fold rather than stir to keep some texture in the kataifi for maximum crunch.

The kataifi should be golden brown and fragrant, with a buttery, nutty aroma. When mixed with the ganache and pistachio cream, the filling should look cohesive, with the pastry strands evenly coated. The mixture should smell sweet and slightly fruity from the raspberry ganache. It should hold together when pressed but not be overly wet. If it seems too dry, add a teaspoon of pistachio cream; if too wet, add a few more toasted kataifi.

Phase 2: Tempering & Molding

3. 3Temper the Ruby Chocolate
   Melt the ruby chocolate in a heatproof bowl set over a saucepan of barely simmering water, stirring until smooth. Heat to 113°F (45°C), then cool to 83°F (28°C) while stirring constantly.
   Look for The chocolate should be glossy and smooth, with no lumps, and register 83°F (28°C) on a thermometer.
   Tip Do not let any water touch the chocolate; even a drop can cause it to seize.
4. 4Mold the Bars
   Pour a thin layer of tempered ruby chocolate into the bar molds, spreading it up the sides. Tap the molds gently to release air bubbles. Reserve enough chocolate for the base.
   Look for The chocolate shell should be even and cover the entire interior of the mold.
   Tip Use a small offset spatula or the back of a spoon to spread the chocolate evenly.
5. 5Fill and Seal
   Spoon the kataifi filling into the chocolate-lined molds, pressing down gently. Pour the remaining ruby chocolate over the filling to seal, smoothing the tops with a spatula.
   Look for The filling should be completely covered by the chocolate; the tops should be level.
   Tip Tap the molds again to settle the chocolate and remove any trapped air.

The tempered chocolate should be glossy and smooth, with a temperature of 83°F (28°C). When poured into the molds, it should coat the sides evenly and have no air bubbles. The filling should be evenly distributed, and the chocolate base should completely cover it.

The molds should be tapped to settle the chocolate, and the tops should be level. The chocolate should look shiny and have a slight give when pressed, indicating it is properly tempered.

Phase 3: Chilling & Final Touch

6. 6Chill and Set
   Place the molds in the refrigerator and chill for 20 minutes, until the chocolate is completely set and firm to the touch.
   Look for The chocolate should be hard and release cleanly from the mold edges.
   Tip Do not skip the chilling time; it ensures clean release and a crisp snap.
7. 7Unmold and Finish
   Carefully unmold the bars. Sprinkle the crushed freeze-dried raspberries over the tops, pressing lightly to adhere.
   Look for The bars should release easily and have a shiny, smooth surface.
   Tip If the chocolate sticks, let the molds sit at room temperature for 2 minutes before unmolding.

After chilling, the bars should be firm and the chocolate should have a hard, glossy surface. When unmolded, they should release easily with no sticking. The tops should be smooth, and the crushed raspberries should adhere. When you break a bar, it should snap cleanly, revealing a crisp, layered interior. The aroma should be a mix of chocolate, raspberry, and pistachio. The bars should be ready to serve immediately.

Common mistakes

One common mistake is overtoasting the kataifi, which can burn and become bitter. Keep a close eye and stir constantly. Another issue is under-tempering the chocolate, leading to a dull, soft shell. Ensure the chocolate reaches 113°F (45°C) and then cools to 83°F (28°C) before using.

If the chocolate seizes (becomes thick and lumpy), it might be due to water contact; start over. When filling the molds, avoid overfilling, as the chocolate may overflow. Finally, do not skip the chilling time—it's essential for clean unmolding.

How to tell it’s done

The bars are done when the chocolate shell is firm to the touch and releases cleanly from the mold. The filling should be set but slightly soft, and the kataifi should remain crisp. If you insert a toothpick into the center, it should come out mostly clean, with a bit of ganache clinging to it.

The chocolate should have a glossy sheen and snap when broken. If the bars are too soft, refrigerate for an additional 5 to 10 minutes. There are no raw proteins in this recipe, so no internal temperature check is needed.
