Ingredients

Scale
  • 1 ½ cups (180g) all-purpose flour (or almond flour for gluten-free)
  • ⅓ cup (40g) unsweetened cocoa powder
  • ½ cup (115g) unsalted butter, cold and cubed
  • ¼ cup (50g) granulated sugar
  • 1 large egg, room temperature
  • Pinch of salt
  • 7 oz (200g) dark chocolate (70% cocoa recommended)
  • ½ cup (120ml) heavy cream
  • 3 cloves black garlic, mashed into a paste
  • 1 small roasted beetroot, peeled and pureed (about ¾ cup / 180g)
  • 2 tablespoons unsalted butter, softened
  • 2 tablespoons honey or maple syrup (optional, to taste)
  • 1 teaspoon vanilla extract
  • Pinch of sea salt
  • Fresh beetroot slices or edible flowers (optional, for garnish)
  • Sea salt flakes (optional, for garnish)

Instructions

  1. Prepare the crust: In a food processor, combine the all-purpose flour, cocoa powder, sugar, and salt. Pulse to mix. Add the cold, cubed butter and pulse until the mixture resembles coarse crumbs. Add the egg and pulse just until the dough starts to come together. If it feels too dry, add a teaspoon of cold water at a time.
  2. Chill the dough: Turn the dough onto a piece of plastic wrap, shape into a flat disc, wrap tightly, and refrigerate for at least 30 minutes.
  3. Roll out and blind bake: Preheat the oven to 350°F (175°C). Roll the chilled dough on a lightly floured surface to about ¼ inch (6mm) thickness. Fit it into your tart pan, pressing it into the edges. Trim any excess dough. Line the crust with parchment paper and fill with pie weights or dried beans. Bake for 15 minutes, then remove the weights and parchment and bake for another 8-10 minutes until set but not browned. Let cool completely.
  4. Prepare the filling: Chop the dark chocolate finely and place in a heatproof bowl. In a small saucepan, heat the heavy cream until it just begins to simmer. Pour the hot cream over the chocolate and let sit for 2 minutes, then stir gently until smooth and glossy.
  5. Add black garlic and beetroot: Stir in the black garlic paste, roasted beetroot puree, softened butter, honey (if using), vanilla extract, and a pinch of sea salt. Mix until fully combined and silky.
  6. Assemble the tart: Pour the chocolate mixture into the cooled crust, spreading evenly with a spatula. Refrigerate for at least 2 hours, or until the filling is firm but creamy.
  7. Serve: Remove the tart from the pan carefully. Garnish with thin beetroot slices or a sprinkle of sea salt flakes just before serving.

Notes

Keep butter cold when making the crust to ensure a tender, crumbly texture. Chill the dough before baking to prevent shrinkage. Let the hot cream sit on the chocolate for 2 minutes before stirring to achieve a silky ganache. If the filling separates or looks grainy, whisk gently over a double boiler to bring it back together. Chilling the tart overnight enhances flavor melding and texture. For dairy-free, substitute heavy cream with full-fat coconut milk and butter with coconut oil. Roasting beetroot yourself improves sweetness and color. Use a sharp knife warmed under hot water for clean slices.
