Ingredients

  • 1/4 cup finely chopped blanched almonds
  • 1/4 cup plus 2 tablespoons granulated sugar
  • 1 stick unsalted butter, softened
  • 1 large egg
  • 1 1/2 cups all-purpose flour
  • 1/4 teaspoon baking powder
  • Two 1-pound sweet potatoes
  • 2 large eggs, beaten
  • 1/2 cup granulated sugar
  • 1/2 cup light brown sugar
  • 1/2 teaspoon salt
  • 1/2 teaspoon cinnamon
  • 1/2 teaspoon ground ginger
  • 1 vanilla bean, split and seeds scraped
  • 3/4 cup heavy cream
  • 3/4 cup milk
  • Red Wine Caramel and lightly sweetened whipped cream, for serving

Method

  • Preheat the oven to 350.
  • In a food processor, combine the almonds and granulated sugar and process until the nuts are finely ground.
  • Add the butter and egg and process until creamy, scraping down the side of the bowl.
  • Add the flour and baking powder and process just until a dough forms, scraping down the side of the bowl.
  • Using your fingers, press the dough evenly into a 10-inch fluted tart pan with a removable bottom.
  • Refrigerate for 15 minutes.
  • Line the tart shell with aluminum foil and fill with pie weights or dried beans.
  • Bake the tart shell for about 25 minutes, or until it is just set.
  • Carefully remove the aluminum foil and pie weights and bake the tart shell for 15 to 20 minutes longer, until the shell is crisp and lightly browned all over.
  • Let cool slightly.
  • Poke the sweet potatoes all over with a fork and roast them in the oven alongside the tart shell for about 1 hour, or until they are soft.
  • Let the potatoes cool.
  • Turn the oven temperature down to 325.
  • Peel and puree the sweet potatoes; you should have about 1 1/2 cups (reserve any leftovers for another use).
  • In a medium bowl, whisk the eggs with the granulated sugar and light brown sugar, salt, cinnamon, ginger and vanilla seeds until smooth.
  • Add the 1 1/2 cups of sweet potato puree along with the heavy cream and milk and whisk until blended.
  • Pour the filling into the tart shell and bake for 20 minutes.
  • Using strips of foil or a 10-inch pie crust ring, cover the rim of the tart shell to prevent overbrowning.
  • Bake the tart for about 40 minutes longer, or until the filling is set.
  • Transfer to a rack and let cool completely.
  • Slice the tart into wedges, top with the Red Wine Caramel and whipped cream, and serve.
