- 1/2 cup unsalted butter, chilled and cubed
- 1/4 cup granulated sugar
- 1/4 cup marzipan, grated
- 1 egg yolk
- 2 tablespoons cold water
- 1/4 teaspoon salt
- 1/2 cup heavy cream
- 1/2 cup milk
- 1/2 cup granulated sugar
- 3 egg yolks
- 1/4 cup cornstarch
- 1/4 cup unsalted butter
- 1 teaspoon vanilla extract
- 1/4 teaspoon salt
- 1/2 cup apricot jam
- 1/4 cup sliced almonds

Special Equipment Needed:
- 9-inch tart pan with removable bottom
- Parchment paper
- Rolling pin
- Pastry brush
- Whisk
- Saucepan
- Mixing bowls
- Electric mixer
- Oven

Step-by-Step Instructions:

1. Preheat the oven to 350°F (175°C).

2. In a mixing bowl, combine the flour, sugar, salt, and grated marzipan. Add the chilled and cubed butter and mix until the mixture resembles coarse crumbs.

3. In a small bowl, whisk together the egg yolk and cold water. Add the egg mixture to the flour mixture and mix until a dough forms.

4. Roll out the dough on a lightly floured surface to fit the tart pan. Line the pan with parchment paper and place the dough in the pan. Trim the edges and prick the bottom with a fork.

5. Bake the crust for 15-20 minutes or until lightly golden brown. Remove from the oven and let cool.

6. In a saucepan, combine the heavy cream, milk, sugar, egg yolks, and cornstarch. Whisk until smooth.

7. Cook the mixture over medium heat, whisking constantly until it thickens and comes to a boil.

8. Remove from heat and add the unsalted butter, vanilla extract, and salt. Whisk until the butter is melted and the mixture is smooth.

9. Pour the mixture into the cooled crust and spread it evenly.

10. In a small saucepan, heat the apricot jam until it becomes liquid. Brush the jam over the top of the custard.

11. Sprinkle the sliced almonds over the top of the tart.

12. Bake the tart for 15-20 minutes or until the almonds are lightly golden brown.

13. Remove from the oven and let cool to room temperature.
