For the crust

1. In a food processor, blend together flour, sugar, butter, and salt just until mixture resembles coarse crumbs with some roughly pea-size butter lumps. Drizzle 3 tablespoons ice water evenly over the mixture and pulse in processor until incorporated.
2. Squeeze a small handful together. If it doesn’t hold together, add more ice water, ½ tablespoon at a time, pulsing until just incorporated, then test again. I usually end up using 4 tablespoons of water.
3. Gather dough together into a ball, then flatten into a ½-inch thick disk. Wrap dough in plastic and chill until firm, about 1 hour.
4. Roll out dough into a large thin round on a lightly floured surface with a floured rolling pin. Using a bowl or plate as a guide, cut out 3 7-inch circles. Transfer the rounds to 3 6-inch tartlet pans with removable bottoms. Ease dough into the pans and pat firmly into the bottoms and up the sides of the pans. Trim off any excess dough by gently running a rolling pin across the top of each pan. Gather dough scraps and roll out another thin round large enough to cut out another 7-inch circle. Fit dough into fourth 6-inch tartlet pan, trimming any excess dough with the rolling pin again. Chill dough in tartlet pans until firm, about 30 minutes.
5. Preheat oven to 375 degrees. Remove tartlet pans from the fridge and place on rimmed baking sheet. Dock the bottom of each pie crust with a fork. Line each tartlet pan with parchment paper making sure parchment paper is firmly pressed up against the bottom edge of crusts. Fill each pan with dried beans or pie weights. Blind bake pie crusts just until they begin to brown, 20-25 minutes. Remove parchment paper and weights. Continue to bake until the crusts are golden, 7 to 10 minutes more. Remove tartlet pans from oven and set on cooling rack. Allow crusts to cool completely before adding the filling.

For the filling

1. Place 3 cups sliced strawberries in a bowl. Set aside.
2. Place remaining 1 1/2 cups of sliced strawberries in a small saucepan. Mash the strawberries with a potato masher until strawberries are broken up and have released their juices. Add in cornstarch, lemon juice, and sugar. Stir until cornstarch is completely dissolved. Heat strawberry mixture over medium heat until mixture comes to a simmer, stirring constantly. Continue cooking until mixture thickens and sauce is translucent, 1-2 minutes more. Remove from heat. Cool mixture about 5 minutes, stirring occasionally.
3. Pour glaze over strawberries in bowl and gently mix until all the strawberries are evenly coated.

For serving

1. Divide strawberry filling among the pie crusts. Whip the cream with the sugar until soft peaks form. Top each pie with a dollop of whipped cream and serve.
