Heat butter and oil in a frypan, add pine nuts and cook until golden brown. Remove and drain on absorbent paper.

Add onion and until softened. Add garlic, lamb and currants and cook until lamb is well browned. Stir in tomato, spices and season to taste, cook for 1-2 minutes. Remove and cool.

Lay a sheet of filo pastry on a clean bench and brush with melted butter. Fold in half widthways. Spread 1 tablespoon of lamb mixture along longer length of pastry. Tuck in edges of pastry and roll up tightly, to form a 'cigar. Place on baking paper lined tray and brush with remaining butter. Repeat with remaining filling, pastry and butter. Bake at 200°C for 10-12 minutes or until golden and crispy.
