                We make the shells for these tarts with packaged graham cracker crumbs to save time. If your brown sugar contains hard lumps, force it through a sieve before using. Otherwise, it won't dissolve in the filling.

                                            Stir together graham cracker crumbs, granulated sugar, and butter in a bowl with a fork until combined well, then press mixture with your fingers and back of a spoon evenly and firmly onto bottom and up side of each tart pan. (If using ramekins, press mixture 3/4 inch up sides.)

                                            Put tart pans on preheated baking sheet and bake crusts until slightly darker, about 10 minutes, then cool 10 minutes on a rack. (Ramekins will need to cool an additional 5 minutes in refrigerator.) Gently push bottom of each tart pan to loosen crust, then invert crust onto your hand and place on a serving plate. (If using ramekins, leave crusts in ramekins.)

                                            While crusts cool, whisk together brown sugar, sour cream, and vanilla in a small bowl until sugar is dissolved. Beat cream cheese in a medium bowl with an electric mixer until smooth, then add sour cream mixture and zest, beating until just combined well.
