  2. Add the eggs a little at a time, then add the sifted flour with the baking powder and salt.
  3. Form a ball of dough, wrap it in plastic wrap, and let it rest in the refrigerator for at least one hour.
  4. Roll out the pastry and line a shallow cake pan that has been previously buttered and floured.

  3. Pour the mixture while still hot over the cocoa butter and mix well.
  4. Stir in the squeezed gelatin sheets, and only once the mixture has cooled slightly (thinned out), add the lime zest.

  • 120 g fresh cream
  • 1 lime zest

Instructions

5. Green Gelatin for Decoration

Ingredients

  • 200 g lime juice
  • 10 g gelatin sheets
  • 1 lime zest

Instructions

  1. Soak the gelatin sheets in cold water.
  2. Heat about 1/3 of the lime juice and dissolve the well-squeezed gelatin in it. Add the rest of the cold lime juice and the lime zest.
  3. Pour the liquid into a shallow mold to a thickness of about 3-4 mm and place in the freezer.
  4. Once frozen, cut out small discs using a pastry cutter.

Assembling the dessert

  1. Take the baked shortcrust shell and spread a thin layer of warm lime cream on the bottom. Place in a blast chiller (or freezer) to set.
  2. Make a second thin layer with the lime and aloe vera gelatin and blast chill again.
  3. Make a third layer with another thin layer of lime cream and return to the blast chiller.
  4. Finish by pouring the white chocolate and lime ganache, creating the final thin layer. Let the dessert cool completely.
  5. Decorate the center of the cake with the frozen green jelly discs and serve.
