1/3 cup sugar
1 tablespoon fresh lemon juice
1 teaspoon cornstarch
2/3 cup all-purpose flour
1 teaspoon baking powder
3/4 teaspoon ground cardamom
1/2 cup heavy cream
Preheat oven to 400� F. and butter an 8-inch (1 1/2-quart) glass pie plate. In a bowl toss together blueberries, zest, sugar, lemon juice, and cornstarch until combined well and transfer to pie plate.
