For the Crust:
1 ½ cups AP flour, plus some to roll dough
6 tablespoons butter, cut into small pieces
6 to 8 tablespoons cold water
1 ½ teaspoons salt
Non-aerosol cooking spray
For the Red Sauce:
2 tablespoons EVOO
2 small cloves garlic, grated or finely chopped
1 pound fresh tomatoes, peeled, cored and finely chopped, or one 13.5-ounce can crushed tomatoes
4 ounces passata
1 fresh bay leaf
2 tablespoons finely chopped flat parsley
Salt and pepper
A few small leaves of basil, torn, plus a sprig, to serve
For the Mornay Sauce:
2 tablespoons butter
2 tablespoons flour
1 cup warm milk
A few grates of nutmeg
A pinch of white pepper
½ cup grated Parmigiano-Reggiano and/or Gruyere cheeses combined
Preheat oven to 450°F, with rack at center.
For the crust, cut the flour with butter, then add cold water and salt, form dough and knead. Wrap and chill 30 minutes. Roll out dough into 12-inch disc on floured surface and place on sprayed baking tray or pizza pan. Weight the top of dough with dried beans on parchment. Bake to brown edges and crisp.
For the red sauce, heat EVOO, 2 turns of the pan, over medium heat. Add garlic and swirl a minute, add chopped fresh or canned tomatoes, passata, bay, parsley, salt and pepper, then simmer 15 to 20 minutes to thicken and smooth the sauce. Add a few small leaves of basil, torn, and remove bay.
While the red sauce cooks, melt butter in saucepan for Mornay sauce. Whisk in flour and warm milk and add a few grates of nutmeg and white pepper. Add the grated cheese or cheeses and taste to adjust seasoning. Funnel thickened sauce into a squeeze bottle with top heavily trimmed to widen nozzle.
Spread sauce on crust to the edges and top with a generous swirl of Mornay sauce and the basil sprig.
