Blood Orange Marmalade Tart

Blood Orange Marmalade Tart

Blood Orange Marmalade Tart
Jam filled lattice-topped tarts are popular all over Italy. In Rome they prefer cherry jam. Some tarts are prepared with apricot or berry preserves. At the Vineria Cozzi in Bergamo Alta they serve a Crostata di Marmellata delle Suore Trappiste, filled with jam made by the Trappist nuns. This recipe takes a home made orange marmalade and binds it with eggs and cornstarch. Blood oranges, now available at our markets, would add their special perfume and color, to the tart.

Prep Time: 45 minutes
Cook Time: 50 minutes
Total Time: 1 hour 35 minutes

Yield: 8 servings

Ingredients
Pasta Frolla for two crusts:
2 1/2 cups all purpose flour
pinch salt
4 to 6 tablespoons sugar
12 tablespoons chilled unsalted butter
3 to 5 tablespoons ice water, as needed

Filling:
3 large navel oranges or 5 to 6 blood oranges
1 1/3 cups sugar
juice of 1 lemon
1/2 cup water
3 tablespoons cornstarch
4 tablespoons unsalted butter, softened
3 eggs
3 tablespoons Grand Marnier or other orange liqueur

Preparation
For the Crust:

  1. Put the flour and salt and sugar in the container of a food processor or mixing bowl. Cut in the butter and pulse until the mixture resembles cornmeal. Gradually beat in the ice water. Turn dough out onto work surface and form into 2 flattened discs, one slightly larger than the other. Wrap in plastic and chill for at least an hour.
  2. Roll out the large disc between very lightly floured sheets of baker’s parchment until you have a circle that is 13 inches in diameter. Carefully ease it into a 9 inch pie plate or 10 inch tart tin with a removable bottom. Chill the crust.

For the filling:

  1. Wash and dry the oranges. With a sharp peeler carefully remove all of the zest from all 3 oranges and chop finely. Separate the oranges into segments and put them in a medium saucepan along with the chopped zest, 1/3 cup sugar, the lemon juice and the water. Bring to a boil and simmer for about 20 minutes, stirring form time to time. Let the mixture cool to room temperature. The filling can be made a day ahead of time and left at room temperature.
  2. Preheat oven to 450 degrees F.
  3. Place remaining sugar in a mixing bowl with the cornstarch and mix with a fork. Add the butter and beat until smooth and fluffy. Beat in the eggs, one at a time. Fold in the cooled marmalade and the Grand Marnier.
  4. Pour the filling into the pie crust. Roll out the remaining pastry between lightly floured sheets of baker’s parchment into a rectangle about 9 by 12 inches. Remove the top piece of parchment and cut into strips with a pastry wheel. Moisten the edge of the crust with a bit of water and then arrange the strips like a lattice on top of the filling.
  5. Bake 10 minutes then reduce the oven temperature to 350 degrees F and continue to bake the tart for 30 to 40 minutes or until filling is set and crust is slightly colored.
  6. Cool and serve with whipped cream.
