For the dough, mix everything except margarine and water. Roughly chop the margarine and add it to the bowl and mix with a hand mixer until there are only small peas left of the margarine. Then add the water and knead everything well. Chill the dough for at least 1 hour.
Preheat the oven to 180 ° C. Grease the hollows of two muffin sheets.
Simply mix all the ingredients together for the filling.
Roll out the dough about 2-3 mm thick on a work surface dusted with flour and cut out circles with a glass, for example. Press the dough circles into the hollows of the muffin tin. Spread the filling evenly in it. Perhaps put a walnut half in the middle for decoration.
