Defrost the puff pastry side by side on the foil (lying between the slices). Meanwhile peel the mangos and cut the flesh from the stone. Cut the fruit flesh crosswise into thin slices.
Wash the lime in hot water and grate dry. Use a zest ripper to tear off the skin and set aside for decoration. Halve the lime and squeeze it. Mix honey and lime juice. Spread mango slices in the middle of the dough.
Mix the egg yolk and cream. Coat the edges of the dough with it. Spread mango with lime-honey mixture. Spread the mango cushions on 2 baking trays lined with baking paper and bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 15-20 minutes until golden brown.
Take out the mango cushion, let it cool down a little, dust with icing sugar and sprinkle with lime zests.
