THE PASTRY... In a small bowl, whisk the cream & egg yolk.

In a large bowl, combine the 1 1/4 cups plus 2 tablespoons of flour with the sugar and salt. Cut the butter into the dry ingredients until the mixture resembles coarse meal. Using a spatula, stir in the yolk mixture. With your hands, knead the pastry just until it comes together. Wrap in plastic and refrigerate for at least 1 hour.

Preheat the oven to 375° and coat a 9-inch fluted tart pan with vegetable oil spray. On a floured work surface, roll out the pastry to a 12-inch round and place it into the pan, pressing it into the corners.

Bake in the center of the oven for 20-25 minutes, until golden brown. Let cool completely.

MEANWHILE, MAKE THE FILLING In a large saucepan, combine the whole eggs, egg yolks, sugar, lemon juice and salt and whisk until smooth. Cook the custard over moderate heat, whisking constantly, until thickened, about 3 minutes. Remove from the heat and add the butter a few pieces at a time, gently whisking until incorporated. Scrape the filling into the cooled tart shell and refrigerate until chilled, about 2 hours.

Serve with whipped cream for a light refreshing dessert.
