- 1 1/2 cups all-purpose flour
- 1 tablespoon plus 1 teaspoon sugar
- 8 tablespoons (1 stick) cold unsalted butter, cut into pea-sized bits
- 1 egg beaten with 1 cup ice water
- Egg Wash, recipe follows
- Cashew Filling, recipe follows
- 2 cups (10 ounces) roasted unsalted cashews
- Egg Wash:
- 2 tablespoons water
- 1 tablespoon flour
- 1 egg yolk
- Cashew Filling:
- 3/4 cup sugar
- 4 eggs
- 1 cup dark corn syrup
- 2 tablespoons dark rum
- 1 tablespoon vanilla extract
- 4 tablespoons unsalted butter, melted
In a large bowl, stir the flour and sugar together. Using a pastry blender or your fingertips, work the butter into the mixture until it resembles coarse meal. Sprinkle on 3 to 4 tablespoons of the eggy water, and mix it in with your fingers until the dough comes together into a ball. Working on a lightly floured surface, take egg-sized pieces of the dough and smear them away from you with the heel of your hand into 6-inch streaks. Scrape up all the streaks of dough and pile them on top of one another to form a disc. Wrap in plastic and refrigerate for at least 2 hours or overnight.
Set a rack in the middle of the oven and preheat to 400 degrees F. Lightly butter a 9 1/2-inch tart pan with a removable bottom.
On a lightly floured surface, roll the dough into an 11 1/2-inch circle. Fit the dough into the prepared pan. Trim the excess dough to a 1-inch overhang and double the dough over itself to reinforce the sides (save the trimmings for any emergency patchwork). Refrigerate for 20 minutes.
Line the tart shell with aluminum foil and weight down with dried beans or pie weights. Bake for 20 minutes. Remove the foil and bake for 5 minutes longer or until lightly browned. Patch any visible holes in the shell with the reserved dough scraps. Brush the shell with Egg Wash and return to the oven for 5 more minutes, until the wash is shiny and no longer runny. Transfer to a rack to cool and lower the oven temperature to 325 degrees F.
Spread the cashews in the partially baked shell and cover with the Cashew Filling, making sure the nuts are covered. Bake for 30 minutes or until little bubbles appear around the edges of the tart and the center looks barely set. Transfer to a rack to cool.Egg Wash:
