Making an Earl Grey Baked Cheesecake can be a straightforward yet rewarding process. Follow these steps to create your delightful dessert:

1. Preheat the Oven: Preheat your oven to 325°F (160°C). Grease a 9-inch springform pan.

2. Make the Crust: In a mixing bowl, combine the graham cracker crumbs, melted butter, and ⅓ cup sugar. Stir until well mixed. Press the mixture firmly into the bottom of the prepared springform pan.

3. Infuse the Cream Cheese: In a small saucepan, heat ½ cup of heavy cream over low heat. Add the Earl Grey tea leaves (or tea bags) and allow it to steep for about 10 minutes. Strain out the leaves or remove the bags, and let the infused cream cool slightly.

4. Beat the Cream Cheese: In a large bowl, beat the softened cream cheese using an electric mixer until smooth and creamy.

5. Combine Ingredients: Gradually add 1 cup of granulated sugar to the cream cheese, beating until combined. Add in the eggs, one at a time, mixing on low speed after each addition until just blended.

6. Add Flavorings: Mix in the vanilla extract, sour cream, lemon zest, and lemon juice. Finally, stir in the cooled Earl Grey-infused cream until evenly combined.

7. Pour the Mixture: Pour the cheesecake mixture over the prepared crust in the springform pan and smooth the top.

8. Bake: Place the cheesecake in the preheated oven and bake for 50-60 minutes, or until the edges are set but the center is slightly jiggly.

9. Cool: Once baked, turn off the oven and leave the cheesecake inside for an additional hour to cool gradually. Then, remove from the oven and cool completely at room temperature.

10. Chill: Once cooled, cover the cheesecake and refrigerate for at least 2 hours, or overnight, for the best flavor and texture.
