Ingredients

  • 1 butter cookie dough disk (see related recipe at left), at cool room temperature
  • 2 eggs
  • 1 1/2 cups sugar
  • 1 tsp. grated lime zest, preferably from Key limes
  • 1/2 cup fresh lime juice, preferably from Key limes (7 or 8 limes)
  • 1/4 cup all-purpose flour
  • 1/4 cup heavy cream
  • Whipped cream for serving (optional; see note above)

Instructions

  • <b>Partially bake the crust</b>
  • Put the dough disk between 2 large sheets of parchment paper and roll out into a 12-inch round about 1/4 inch thick. Fold the dough round in half and transfer to a 10 1/2-inch tart pan with a removable bottom. Unfold the round and ease it into the pan, patting it firmly into the bottom and up the sides. Trim the edges to form a 1/2-inch overhang. Fold the overhang back over itself and press it into the sides of the pan. Freeze for at least 30 minutes or up to overnight.
  • Preheat an oven to 375°F.
  • Line the crust with aluminum foil and fill with pie weights. Place the pan on a baking sheet and bake for 10 minutes. Remove the foil and weights and continue to bake until the crust is set and lightly golden, about 5 minutes. Transfer the pan to a wire rack and reduce the oven temperature to 350°F.
  • <b>Make the filling</b>
  • In a large bowl, whisk together the eggs, sugar, lime zest and lime juice until smooth, about 1 minute. Whisk in the flour until incorporated. Whisk in the 1/4 cup cream until blended. Pour the filling into the partially baked crust.
  • <b>Bake the tart</b>
  • Bake until the filling looks set when you gently shake the pan, about 30 minutes. Transfer the pan to a wire rack and let stand until the top feels cool to the touch, about 1 hour.
  • Remove the tart from the pan, cover and refrigerate until cold, at least 3 hours or up to overnight. Cut the tart into wedges and serve topped with whipped cream. Serves 8.
