Instructions
- Preheat the oven to 350 degrees F (175 degrees C). Lightly grease a 9 inch tart pan with a removable bottom.
- Cook 21 ounces blackberries in a large pot over medium heat, until berries pop and release juices, about 10 minutes. Press berries through a fine mesh sieve over a large bowl using the back of a wooden spoon, collecting approximately 1 cup juice. Discard seeds and pulp. Cool, about 30 minutes.
- Pulse flour, almonds, and ¼ teaspoon salt in the bowl of a food processor until combined and almonds are finely ground. Add in 3 tablespoons butter, maple syrup, and vanilla extract: pulse until mixture is crumbly and resembles wet sand. Press maple mixture into the bottom and sides of the prepared tart pan.
- Bake in the preheated oven until the edges of the crust are lightly browned, about 20 minutes. Cool on a wire rack.
- Whisk sugar, cornstarch, and ¼ teaspoon salt together in a large heat safe bowl. Mix in cooled blackberry juice, eggs, egg yolk, lemon juice, and lemon zest until smooth.
- Bring a pot of water to a low simmer. Place the bowl with blackberry mixture over the pot, never to touch the water. Cook, stirring constantly, until mixture thickens, about 10 minutes. Off heat, stir in 3 tablespoons butter, one piece at a time, ensuring each piece melts before the next addition. Strain custard mixture through a fine mesh sieve into the prepared crust.
- Bake in the preheated oven until filling is just set, 20 to 25 minutes. Cool. Top with reserved 1 cup blackberries just before serving.
