Instructions
Make the lemon purée:
Wash the lemons and cut them into pieces. Discard the seeds. Transfer the lemons and the sugar to food processor and purée until smooth.
Scrape the purée into a small saucepan and bring to a simmer, stirring to dissolve the sugar. Remove from the heat and cool completely.
Preheat oven to 375°F.
Line a cookie sheet with parchment paper
On a lightly floured work surface, roll out the puff pastry (you can trim the edges so they're straight).
Cut the pastry into 2x3-inch rectangles (I ended up with 15 rectangles). Arrange the rectangles on the parchment paper line cookie sheet and brush with the egg wash.
Bake the pastry until lightly golden, about 12 minutes. When cool enough to handle, spread a tablespoon of the lemon purée over each of the rectangles and return to the oven for 7 to 8 minutes longer. Remove from the oven and cool down completely.
Make the whipped cream:
Beat the cream with the sugar in a medium bowl until firm peaks form (I use a standup mixer). Scrape the whipped cream into a pastry bag fitted with a round tip.
Slice the baked pastry shells open transversely. Pipe some of the whipped cream on the bottom shell and top with the top shell.
Notes
The lemon purée can be made ahead of time and refrigerated for up to two weeks
