Deep-Dish Cranberry-Cassis Pie
Marinate the filling: Place the cranberries in a large bowl.
Add the orange zest, cassis, and Grand Marnier and toss to combine.
Cover and let marinate at room temperature overnight.
The next day, drain the liquid from the cranberries into a medium saucepan.
Stir in the sugar and cornstarch.
Pour the sauce over the cranberries and stir in the candied ginger.
Preheat the oven to 350 F.
Beat the egg and water in a small bowl and brush over the pastry.
Place the pan on a baking sheet to catch any drips.
