(Tarte au Citron)
This is the way French chef Sylvain Cudelou of Aux Tonneaux des Halles made his scrumptious tart for us.
For The Pastry:
2 1/2 cups flour
1/2 cup superfine sugar
1 egg yolk
16 tbsp. butter, cut into small pieces
For The Filling:
1 1/4 cups sugar
1 cup fresh lemon juice
6 tbsp. heavy cream
1. For the pastry: Preheat oven to 375°. Sift together flour, sugar, and salt into a mixing bowl. Beat together 1 of the eggs and the yolk in a small bowl, then add eggs, along with the butter, to the flour mixture. Use a pastry cutter or 2 knives to work butter and eggs into flour until mixture resembles coarse meal. Transfer to a clean surface and, working with a handful at a time, knead mixture with the heel of your hand into a smooth dough. Gather together and knead briefly to form a smooth ball, then dust with flour.
2. Roll dough out on a lightly floured surface into a 14" round, then carefully ease into a 12" false-bottomed tart pan. (Pinch dough back together if it tears or cracks.) Run rolling pin over the top of the pan to cut off overhanging dough, then prick crust with a fork. Line dough with parchment paper, add pie weights or dried beans, and bake on a cookie sheet until edge of crust is golden, about 25 minutes. Beat remaining egg in a bowl. Remove parchment and weights from crust, brush bottom with egg, and continue baking until crust is golden, 5–7 minutes more. Set aside to cool.
3. For the filling: Reduce oven to 300°. Beat eggs and sugar in a medium bowl until thick and well mixed. Gradually add lemon juice, then cream, whisking constantly. Pour filling (you may have a little extra) into prepared crust and bake until filling is set, about 40 minutes. Allow to cool completely before serving.
