Prep Time: 2.5 hours Cook Time: 1.5 hours
For the pistachio crust:
- ½ cup unsalted, shelled pistachios
- 1 ½ cups all-purpose flour
- ½ cup confectioner’s sugar
- ¼ tsp sea salt
- 1 large egg
- 130g unsalted butter, cut into small cubes and frozen
For the filling:
- 1-2 lemons, rinsed and dried
- 1½ cups sugar
- ½ cup unsalted butter, cut into chunks
- 4 large eggs
- 2 tbsp cornstarch
- ¼ tsp sea salt
For the brûlée top:
- 1-2 tbsp granulated sugar
- Prepare a baking sheet, spread pistachios on it and roast for 5 minutes until they are fragrant. Remove and grind into a fine powder. Mix the pistachio powder, flour, sugar, and salt together in a large bowl. Cream in the butter. Add in the egg and blend until smooth. Remove mixture from bowl and wrap in plastic wrap, chilling for 2 hours.
- Then roll the dough into a 12-inch circle on a lightly floured surface. Transfer to a 9-inch tart-pan, press into the sides and corners of the pan. Trim dough so there is a ½-inch overhang and then fold the overhang in to make the sides thick. Poke the bottom and sides of the tart dough with a fork and freeze for 30 minutes.
- Preheat oven to 180C°. Butter the shiny side of a piece of foil then press tightly against the crust. Place tart pan on a baking sheet and bake for 20-25 minutes. Remove the foil, using the back of a spoon to press down all the bubbles. Bake for 5 more minutes uncovered. Set aside and let the crust cool to room temperature.
- While the crust is cooling, slice lemons into thin rounds then remove the end pieces and seeds. Place slices into a food processor together with sugar and butter chunks, and blend until the lemon is fully pureed. Then add the eggs, salt and cornstarch and process until a smooth batter is formed.
- Pour into the crust until filling is level with the top of the crust (do not overfill). Bake for 35-40 minutes, until the edges are brown and only jiggles slightly when moved. Let cool on a rack for 30 minutes. Fully chill in the refrigerator.
- Right before serving, sprinkle an even layer of granulated sugar on the top of the tart, then caramelize the sugar using a kitchen torch. When the brûléed top is formed. cut and serve immediately.
