Melt the butter. Finely dice the apricots. Finely chop almonds and pistachios. Mix with honey, lemon juice and spices. Cut dough triangles in half lengthwise and brush with melted butter.
Place 1 teaspoon of apricot mixture on each broad end of a triangle and roll up towards the top. Brush with butter. Place the rolls on two baking trays lined with baking paper. Bake the trays one after the other in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 15-20 minutes until golden brown.
Place the rolls on a cake rack and spread with syrup. Dust with icing sugar and decorate with mint.
