1. Place the chillies, ginger, corander, cumin, mint, garlic, oil, cloves and cardamom into a food processor and process until fairly smooth. Transfer to a mixing bowl, then add the minced beef and season with salt. Mix well with your hands.
2. Divide the mixture into 12. Cover and chill for 30 minutes in the fridge if you have time.
3. Lightly oil 12 flat metal skewers and shape the kebab mixture around each skewer (as if making a sausage shape).
4. Place the seekh kebabs under a preheated grill and cook for around 5 minutes on each side or until the kebabs are cooked through.
5. Serve the kebabs with sliced red onions and chopped mint if desired.
