- 1 1/2 cups plus 2 tablespoons all-purpose flour
- 4 tablespoons sugar
- 1 1/2 cups pine nuts (about 5 ounces), toasted
- Pinch salt
- 1 stick (4 ounces) unsalted butter, melted and cooled slightly
- 1/2 cup water
- 1 cup ricotta cheese
- 6 ounces cream cheese, at room temperature
- 2 large eggs
- 3 large egg yolks
Preheat the oven to 350 degrees F.
In the bowl of a food processor, pulse flour, 2 tablespoons of sugar, 3/4 cup of pine nuts, and salt until finely ground. Add the butter. Pulse dough just until it comes together.
Line the tart shell with aluminum foil and fill with pie weights or dried beans. Bake the tart shell in the lower third of the oven until just set, about 25 minutes. Carefully remove the foil and pie weights. Bake until the tart shell is lightly golden, about 10 minutes. Cool completely.
Combine the remaining 2 tablespoons of sugar with the water in a small saucepan over low heat. You don't want to boil the water, you just want to heat it so that the sugar can dissolve thoroughly. Stir until the sugar dissolves and remove from heat.
In the bowl of a food processor, pulse the ricotta cheese and cream cheese until smooth. Add the eggs and egg yolks, 1 at a time, and process until smooth. With the machine running, add the sugar syrup in a thin steady stream and process until smooth.
Pour the custard into the tart shell and bake until the filling is almost set, about 20 to 25 minutes. Scatter the remaining 3/4 cup of toasted pine nuts atop the filling. Bake until the custard is set, about 10 minutes longer. Let the tart cool completely before serving.
The tart can be wrapped in plastic and refrigerated for up to 3 days. Return the tart to room temperature before serving.
