Roast lamb with rosemary

Here's a dish I tried over the recent Xmas with family..

Ingredients
Leg of lamb
Rosemary sprigs, garlic
Fennel & cumin seeds
Salt & pepper
Tomato ketchup, balsamic vinegar, olive oil
Bay leaves

Prepare the sauce to marinate the lamb. Pound fennel & cumin seeds till fine. Add salt, pepper and pour unto tray. Add couple of tablespoons of olive oil, balsamic vinegar and tomato ketchup. Mix it all together.

Slice the leg of lamb in long slashes. Pour the marinade on the leg of lamb, ensuring that it's well coated. Put it on a roasting tray and cover it tightly with aluminium foil. Put into oven and cook at 180 Celcius for 1.5 hours.

Once ready, open it up and further roast for another 30 minutes to make the outer layer crisp. Let it rest for a while before serving.
