01 - In a bowl, combine graham cracker crumbs, melted butter, and sugar. Mix until evenly moistened.
02 - Press the crumb mixture firmly into the bottom of jars or the base of a 9-inch (23 cm) springform pan. Chill while preparing the filling.
03 - In a large bowl, beat the cream cheese until smooth. Add powdered sugar, vanilla, and lemon zest (if using), mixing until creamy.

06 - Refrigerate for at least 4 hours, or until set.
07 - In a small saucepan, combine strawberries, sugar, and lemon juice. Cook over medium heat for 5-7 minutes, stirring occasionally, until the strawberries are soft and syrupy. Let cool completely.
08 - Before serving, spoon the cooled strawberry topping over the cheesecake. Serve chilled.
