Ingredients

For the Brown Butter Tart Crust (Pâte Sablée Style)

• Unsalted Butter: 150g (approx. 2/3 cup), to be browned
• All-Purpose Flour: 250g (approx. 2 cups)
• Powdered Sugar: 90g (approx. 3/4 cup)
• Almond Flour: 30g (approx. 1/4 cup)
• Egg: 1 large, room temperature
• Fine Sea Salt: ½ tsp

For the Pistachio Praline Paste

• Raw Pistachios: 200g (approx. 1 ½ cups), shelled
• Granulated Sugar: 150g (approx. 3/4 cup)
• Water: 40ml (approx. 3 tbsp)
• Flaky Sea Salt: a generous pinch

For the Pistachio Praline Filling

• Pistachio Praline Paste: 200g (prepared above)
• Brown Butter: 50g (reserved from crust browning)
• Heavy Cream: 100ml
• Large Eggs: 2
• Sea Salt Shavings (Maldon): For finishing

Step-by-Step Instructions

1. Brown the Butter

Place all 200g of butter in a light-colored saucepan over medium heat. Melt and continue cooking as it foams and crackles. Once the crackling stops and you see golden-brown specks at the bottom with a nutty aroma, remove from heat. Strain into a bowl. Reserve 50g for the filling and let the remaining 150g cool until it reaches a soft, spreadable consistency.

2. Prepare the Crust

In a food processor, pulse the flour, almond flour, powdered sugar, and salt. Add the 150g of softened brown butter and pulse until the mixture looks like wet sand. Add the egg and pulse until the dough just begins to clump. Turn out onto a surface, form into a disk, wrap in plastic, and chill for at least 1 hour. Once chilled, roll out to 1/8 inch thickness, line a 9-inch tart pan, and blind bake at 350°F (175°C) for 15 minutes with weights, then 5-8 minutes without weights until golden.

3. Create the Pistachio Praline

Toast pistachios at 325°F (160°C) for 10 minutes. In a saucepan, combine granulated sugar and water. Cook without stirring until it reaches a deep amber caramel. Immediately pour the caramel over the toasted pistachios on a silicone mat. Let cool completely. Break the hardened caramel-nut clusters into pieces and blend in a high-speed food processor until it transforms from a powder into a smooth, liquid paste. Stir in a pinch of sea salt.

4. Assemble the Filling

Whisk together 200g of your fresh pistachio praline paste, the reserved 50g of liquid brown butter, the heavy cream, and the eggs until completely smooth. Pour the mixture into your pre-baked tart shell.

5. The Final Bake & Finish

Lower the oven to 325°F (160°C). Bake the tart for 20-25 minutes until the filling is set but still has a slight wobble in the center. Allow to cool completely at room temperature. Just before serving, sprinkle generously with Maldon sea salt shavings. The salt is essential to cut through the richness of the praline.

Fact-Check: The Science of the Tart

• Brown Butter (Beurre Noisette): The “nutty” flavor comes from the Maillard reaction, where milk solids are toasted. This adds a savory depth that standard butter lacks.
• Praline vs. Paste: A true praline contains caramelized sugar, whereas a “pistachio paste” is often just ground nuts. The caramelization in this recipe provides the characteristic “burnt sugar” undertone.
• Salt Balance: Sea salt shavings (large flakes) provide a targeted burst of salinity that resets the palate, preventing the intense pistachio fats from becoming cloying.
