Cut apricots and plums into very fine cubes. Mix with jam. Roll out 1/3 shortcrust pastry on foil to 2 rectangles (approx. 25 x 15 cm). Carefully spread the prepared mixture on top.
Roll up from the longer side to the middle using the foil. Cut each piece into about 20 pork ears. Place on 2 baking trays lined with baking paper. Bake in a preheated oven (electric: 175 °C/ gas: level 2) for 12-14 minutes
