Roll out the sheet of puff pastry carefully. With shapes, cut out the desired bites. Arrange them in a large tray laid out with baking paper. Smear each bite with a little melted butter, add salt, sprinkle with a little grated cheese and curry. Bake the bites in a moderately heated oven until ready.
When serving, you can put a piece of ham and cucumber on every bite and stick a toothpick through the middle, to be able to grab them more easily.
