Lay out puff pastry slices next to each other on a lightly floured work surface and allow to thaw. Then cut each slice into three equally sized pieces. Spread the tops of the dough evenly with apricot jam.
Then place the puff pastry sheets in the refrigerator for about 10 minutes. In the meantime, put flour, sugar and fat in flakes in a bowl. Work the ingredients into crumbles by hand. Spread the crumbles over the pastry pieces.
Place the puff pastry slices on a cold rinsed baking tray. Bake in the preheated oven (electric: 225 ° C/ gas: level 4) for about 15 minutes until golden brown. Remove the finished puff pastry immediately from the baking tray and let it cool down on a cake rack.
The pastry tastes best fresh. Makes about 15 pieces.
