In a large mixing bowl, combine the minced lamb meat, ginger paste, garlic paste, raw papaya paste, roasted gram flour, red chilli powder, garam masala powder, coriander powder, cumin powder, black pepper powder, and salt. Mix well.
Cover the bowl and refrigerate for at least 3 hours, or overnight.
In a pan, heat 1 tbsp of ghee over medium heat. Add the chopped onion and fry until translucent.
Add the marinated lamb meat to the pan and cook for 20-25 minutes or until the meat is tender and well cooked.
Allow the mixture to cool, then transfer to a blender or food processor and blend until it forms a smooth paste.
Shape the mixture into small round patties or kebabs.
In a separate pan, heat the remaining 1 tbsp of ghee over medium heat.
Add the kebabs to the pan and cook for 2-3 minutes on each side, until they are golden brown.
Garnish with finely chopped coriander and mint leaves.
Serve hot with mint chutney or onion rings.
