2/3 cup sugar
1/4 cup all-purpose flour
1 1/2 cups buttermilk
3 large eggs
2 teaspoons vanilla bean paste
1 (8- or 10-oz.) package frozen tart shells
Toppings: fresh fruit, fresh basil sprigs
How to Make It
Whisk together sugar and flour in a 3-qt. heavy saucepan; add buttermilk and eggs, and whisk until blended. Cook over medium heat, whisking constantly, 7 to 8 minutes or until a pudding-like thickness. Remove from heat, and stir in vanilla bean paste. Cover and chill 4 to 24 hours.
Meanwhile, bake frozen tart shells according to package directions, and cool completely (about 30 minutes). Spoon custard into tart shells, and top with desired toppings just before serving.
