Ingredients

Scale

For the Crust:

  • 1 cup all-purpose flour
  • 1/2 cup ground pistachios
  • 1/2 cup unsalted butter, softened
  • 1/2 cup granulated sugar
  • 1 egg yolk
  • 1/2 tsp vanilla extract
  • 1/4 tsp salt
  • 1 cup heavy cream
  • 1/2 cup powdered sugar
  • 2 tbsp lemon zest
  • 1/4 cup fresh lemon juice
  • 1 tsp gelatin, dissolved in 2 tbsp warm water

Instructions

1. Prepare the Crust:

  1. Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
  2. In a bowl, cream together butter and granulated sugar until light and fluffy. Mix in egg yolk and vanilla.
  3. Add flour, ground pistachios, and salt. Mix until a dough forms. Roll into small balls and flatten slightly on the baking sheet.
  4. Bake for 10-12 minutes until edges are golden. Let cool completely.
  5. For the mousse, whip heavy cream and powdered sugar to stiff peaks. Fold in lemon zest, lemon juice, and dissolved gelatin.
  6. Pipe or spoon lemon mousse onto the bottom of one cookie. Top with another cookie, bottom-side down, creating an upside-down sandwich.
  7. Chill for at least 1 hour before serving.
