03Whisk the yolks until smooth. Very slowly whisk in the hot cranberry mixture. Return mixture to the saucepan and cook over medium heat, stirring constantly, until it thickens a bit, about 5 minutes. (Do not allow to boil, or the eggs will scramble.) Set aside.04To make the filling, place the cranberries, sugar and 1/2 cup water in a small saucepan. Boil just until the sugar melts. Set aside.05Preheat the oven to 400 degrees. Position a rack in the top third of the oven. Have the curd and filling very hot. (Reheat the curd gently, stirring, to avoid scrambling the eggs.)06To make the meringue, put the cornstarch and 1 tablespoon sugar in a small saucepan. Stir in 1/3 cup water. Place over medium heat and stir until the mixture boils and becomes translucent. Set aside. In a medium bowl, beat the egg whites and salt until fluffy. Slowly add remaining sugar. Reduce speed to medium and add cornstarch mixture a tablespoon at a time. Beat just until meringue is glossy and holds stiff peaks. (Do not overbeat.) Fold in the dried cranberries.07Pour off any liquid from the filling and spread it in the pie shell. Top it with the cranberry curd. Add the meringue, covering the filling completely and making little decorative peaks. Place the pie on a baking sheet to catch any drips and bake until meringue peaks are nicely browned, 8 to 10 minutes. Let cool before serving or refrigerating.
