Follow these straightforward steps to prepare your Raspberry Lemon Tart:

1. Preheat the Oven: Set your oven to 350°F (175°C) to ensure it reaches the required temperature while you prepare the tart filling.
2. Prepare the Lemon Mixture: In a mixing bowl, combine the lemon juice, lemon zest, sugar, cornstarch, and salt. Whisk these ingredients together until the mixture is smooth and free of lumps.
3. Add the Eggs: Incorporate the eggs into the lemon mixture. Continue whisking until the eggs are fully integrated, resulting in a uniform consistency.
4. Fill the Crust: Pour the lemon mixture into the pre-made graham cracker crust, spreading it evenly to ensure a consistent bake.
5. Bake the Tart: Place the tart in the preheated oven and bake for 25-30 minutes, or until the filling is set. You can test this by gently shaking the tart; the center should be firm but slightly jiggly.
6. Cool the Tart: Allow the tart to cool at room temperature, then refrigerate it for at least an hour to fully set the filling.
7. Add the Toppings: Just before serving, top the tart with fresh raspberries and a generous dollop of whipped cream. This adds a refreshing layer of flavor and texture.
