Ingredients
- 6 ounces roasted pistachio, shelled
- 3 eggs room temp, separated
- ¾ + ¼ cup powdered sugar
- pinch of salt
- 2 teaspoons freshly grated orange zest
- 1/3 cup freshly squeezed orange juice
- 1 teaspoon vanilla extract
- 1/3 cup Greek yogurt
- 1 ½ teaspoons maple syrup
- 1/2 teaspoon orange zest
- 2 large navel oranges, and 2 mandarins, peeled and sliced into thin pinwheels
Directions
- Preheat oven to 325 Fahrenheit.
- In a blender or food processor, blitz pistachios until they are reduced to a coarse cornmeal texture – a pistachio meal. Set aside.
- In a large mixing bowl, whisk together egg yolks and ¾ cup powdered sugar. Add ground pistachio, salt, orange zest and juice, and vanilla extract. Stir until ingredients are well integrated – the texture will be wet and paste-like.
- In a separate bowl, whisk egg whites and remaining ¼ cup powdered sugar, until soft peaks form. Gently fold egg whites into the pistachio batter. Don’t overmix. A streaky batter is great.
- Prep an 8 or 9-inch cake pan, with a removable bottom. Butter well, then line bottom with parchment. Butter again. Pour in batter.
- Bake for 30-40 minutes, rotating occasionally, until the top of the tart is deeply golden.
- Let tart cool completely on a cooling rack. Gently run a knife around the edges of the tart and remove the outer ring.
- Whisk yogurt with 1 1/2 teaspoons maple syrup + 1 teaspoon orange zest.
- Just before serving, top tart with seasoned yogurt, then gently layer on orange slices.
