Pastry:
1 1/4 cups unbleached all-purpose flour
1/4 tsp salt
1/4 cup plus 2 Tbls water
1/4 cup good extra virgin olive oil
Filling:
4 leeks, green stems removed, washed well and chopped
2 Tbls. olive oil
1/2 cup diced ham
1/2 cup grated Swiss cheese
3 eggs, beaten
1 cup half and half or heavy cream
Dash of nutmeg
Preheat the oven to 400 degrees. For the pastry, combine the flour and 1/4 teaspoon salt in a medium size bowl. Stir in the water and then the oil, mixing until thoroughly blended. Knead briefly. The dough will be very moist, much like a cookie dough. Press the dough into a 10" loose-bottomed metal tart tin.
Saute the leeks in the heated oil over medium low heat until limp. Add the ham and brown slightly. In a bowl combine the beaten eggs, cream and nutmeg. Place the leek mixture into the prepared tart tin. Top with grated cheese. Pour the egg mixture over all and place in oven and bake for 40 minutes.
