Roll out the puff pastry and cut 4 circles about 6 inches wide. Butter 4 single ramekins and line them with the puff pastry. Prick the bottom with a fork and bake in a preheated oven at 325°F for 10-15 minutes. Remove and cool.
Dice the papaya and the Taleggio cheese and season with the oil, salt and pepper. Fill the ramekins with this filling.
Whisk together the Toma Piemontese cheese with the heavy cream and a pinch of salt. Place a dollop over each ramekin, garnish with lemongrass, and serve.
