Ingredients & Instructions
Let’s break down this recipe step by step so you can recreate this classic in your own kitchen—complete with tips to make it foolproof and flavorful.
Ingredients
For the Crust:
- 1½ cups all-purpose flour
- ¼ cup granulated sugar
- Pinch of salt
- ½ cup unsalted butter, cold and cubed
- 1 egg yolk
- 2–3 tbsp cold water
For the Lemon Custard Filling:
- 1½ cups whole milk
- ¾ cup granulated sugar
- 3 large egg yolks
- ¼ cup cornstarch
- Zest of 1 lemon
- ½ cup fresh lemon juice (about 2 lemons)
- 2 tbsp unsalted butter
- 1 tsp vanilla extract
Step-by-Step Instructions
1. Prepare the Crust
In a large bowl, whisk together the flour, sugar, and salt. Cut in the cold butter using a pastry cutter or your fingertips until the mixture becomes crumbly, resembling coarse sand.
Add the egg yolk and 2 tablespoons of cold water, mixing gently until the dough just comes together. If it feels dry, add another tablespoon of water.
Form the dough into a disc, wrap it in plastic, and refrigerate for 20–30 minutes to firm up.
Tip: Keeping the butter cold helps create a tender, flaky crust.
2. Blind Bake the Crust
Preheat your oven to 350°F (175°C).
Roll out the chilled dough and press it evenly into a tart pan or square cake pan. Prick the bottom with a fork to prevent bubbling.
Bake for 12–15 minutes, or until lightly golden. Set aside to cool slightly while you make the custard filling.
3. Make the Lemon Custard
In a medium saucepan, whisk together sugar, cornstarch, lemon zest, and egg yolks until smooth. Gradually pour in the milk, whisking constantly to avoid lumps.
Cook over medium heat, stirring continuously, until the mixture thickens into a pudding-like consistency (about 7–8 minutes).
Remove from heat and stir in the lemon juice, butter, and vanilla extract until everything is fully combined and silky.
Tip: For an extra-smooth custard, strain it through a fine mesh sieve before pouring it into the crust.
4. Assemble and Bake
Pour the warm custard into the pre-baked crust, spreading it evenly with a spatula. Bake for 25–30 minutes, or until the filling is set but still slightly wobbly in the center—it will firm up as it cools.
Allow the cake to cool completely at room temperature, then refrigerate for at least 2 hours before slicing. This step ensures clean slices and a creamy texture.
Optional: Dust with powdered sugar or top with thin lemon slices before serving for an elegant finish.
Cooking Tips & Variations
1. Add a Touch of Almond
For a subtle nutty twist, replace ¼ cup of flour in the crust with almond flour. It pairs beautifully with the lemon flavor.
2. Dairy-Free Option
Use almond milk or oat milk and a dairy-free butter substitute to make this dessert suitable for lactose-intolerant guests without losing its creamy texture.
3. Make It a Tart
Instead of a cake pan, bake the dessert in a fluted tart pan for a classic Italian patisserie look.
4. Add a Whipped Cream Topping
Serve each slice with a dollop of freshly whipped cream or sweetened mascarpone for extra indulgence.
5. Infuse More Citrus
Try mixing in orange zest or a hint of limoncello for a deeper, more complex lemon flavor.
Storage & Serving Suggestions
