Cold-Set Blood Orange & Olive Oil Tart with Dark Cocoa Crust

Instructions

1. 1

   Preheat your oven to 350°F (175°C). In a small saucepan, melt 113g unsalted butter over medium heat. Swirl the pan occasionally. Let it pop and foam until the milk solids drop to the bottom and turn a deep, toasted hazelnut color, about 5-7 minutes. Pour into a bowl to stop the cooking and let it cool slightly. This deep, nutty backdrop is your first layer of contrast.

   Tip: Listen to the butter; when the crackling stops, the water is gone and browning happens fast. Don't walk away.

2. 2

   In a medium mixing bowl, whisk together 120g all-purpose flour, 30g Dutch-process cocoa powder, 50g powdered sugar, and 1/4 tsp kosher salt. Pour in the slightly cooled brown butter and stir with a spatula until the mixture resembles damp, dark sand. Press it firmly and evenly into the bottom and up the sides of a 9-inch removable-bottom tart pan.

   Tip: Use the flat bottom of a measuring cup to press the crust evenly. We’re not adding steps—just improving decisions.

3. 3

   Bake the crust for 15 minutes. It will look dry and smell intensely of toasted cocoa. Set the pan on a wire rack to cool completely. A cold crust means a crisp foundation for our set curd.

   15 min

   Tip: Because the crust is dark, you can't rely on visual browning. Trust your timer.

4. 4

   While the crust bakes, let's prep the filling. In a small bowl, evenly sprinkle 7g unflavored powdered gelatin over 30g cold water. Set aside to bloom. In a medium heatproof bowl, combine 200g freshly squeezed blood orange juice, 10g blood orange zest, 100g granulated sugar, 3 large eggs, and the remaining 1/4 tsp kosher salt.

   Tip: Wipe your counter now. Keeping your workspace clean lowers your heart rate.

5. 5

   Set the bowl of the orange mixture over a saucepan of barely simmering water to create a double boiler. Whisk constantly. We are gently structuring the eggs. Cook until the mixture hits exactly 165°F (74°C) on an instant-read thermometer and lightly coats the back of a spoon. Do not let it boil, or you will ruin the fresh citrus notes.

   Tip: Precision is freedom. Use a thermometer. Guessing leads to scrambled eggs or a runny tart.

6. 6

   Immediately remove the bowl from the heat. Whisk in the bloomed gelatin mass until it is completely and seamlessly dissolved. Pour the mixture through a fine-mesh sieve into a clean, painter's tape-labeled bowl. This removes the spent zest and any tiny egg bits, guaranteeing silk.

   2 min

   Tip: Do not skip straining. Texture engineering is about removing distractions.

7. 7

   Let the strained curd cool at room temperature until it reaches roughly 110°F (43°C)—warm to the touch, but not hot. Slowly stream in 50g fruity extra-virgin olive oil while whisking vigorously to emulsify. Pour this glossy, cohesive filling directly into your cooled cocoa crust.

   10 min

   Tip: If the curd is too hot, the oil will separate and pool. Temperature management is everything.

8. 8

   Carefully transfer the tart to the refrigerator. Let it chill completely undisturbed for at least 3 hours, or until fully set. When ready to serve, slice the tart cold. Let it cool—future you deserves clean slices. Finish each slice with a drizzle of extra olive oil and a pinch of to taste flaky sea salt.

   Tip: Run a thin, sharp knife under hot water and wipe it dry before slicing for absolute perfection.
