Clean and wash the chicken drumsticks; pat dry.
Prick or score the flesh to allow the marinade to infuse well.
Grind all the spices (black pepper, coriander, cumin, cinnamon, chilli) to a coarse powder.
Add this to the chicken drumsticks along with a pinch of saffron, lemon juice, olive oil and salt. Mix well and marinate for at least 2-3 hours (preferably overnight).
Preheat the oven to 180°C (fan forced oven).
Line an oven proof tray with baking paper and place the chicken drumsticks.
Bake for 20-25 minutes (turn once halfway through) or till the chicken has cooked well.
Remove from oven, rest for 5 minutes before serving.
Garnish with coriander leaves and serve with lemon wedges.
