Creating a stunning Strawberry Mousse Tart is easy when you follow these steps:

Prepare the Tart Crust

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Mix the Dough: In a mixing bowl, cream together the softened butter and sugar until light and fluffy.
3. Add Egg Yolk: Incorporate the egg yolk and mix until fully combined.
4. Add Flour: Gradually add in the flour, mixing until the dough starts to come together. If needed, add cold water, one tablespoon at a time, until the dough is not sticky.
5. Form the Crust: Press the dough into the bottom and up the sides of a tart pan evenly.
6. Chill: Refrigerate the crust for 15-20 minutes.
7. Bake: Once chilled, bake the tart crust for 20-25 minutes until lightly golden. Remove from the oven and let it cool completely.

Prepare the Strawberry Mousse

8. Prepare Gelatin: In a small bowl, combine the gelatin with 4 tablespoons of water and let it stand to bloom for about 5 minutes.
9. Blend Strawberries: In a blender, puree the fresh strawberries with sugar and lemon juice until smooth.
10. Heat Gelatin: Gently heat the bloomed gelatin in the microwave for about 10-15 seconds until dissolved. Stir the dissolved gelatin into the strawberry puree.
11. Whip the Cream: In a separate bowl, beat the heavy cream and vanilla until soft peaks form.
12. Combine Mixtures: Gently fold the whipped cream into the strawberry mixture until well combined. Be careful not to deflate the mousse.

Assemble the Tart

13. Fill the Tart: Pour the mousse mixture into the cooled tart shell, smoothing the top with a spatula.
14. Chill: Cover and refrigerate the tart for at least 2-3 hours to allow it to set properly.
15. Garnish: Once set, top the tart with fresh strawberry slices and mint leaves for decoration.

Serve

16. Slice and Serve: Carefully remove the tart from the pan, slice, and serve chilled. Add a dollop of whipped cream on the side if desired.
