How to cook
Mix all of the ingredients for the marinade in a bowl. Put the leg of lamb in an oven dish and smear it thoroughly with the spicy mixture. Pour in water and cover with foil.
Bake at 356°F (180 °C) for 1 hour. Then decrease the heat to 320°F (160 °C) and bake for another 2 hours or so.
Finally, remove the foil and finish baking the leg of lamb until it obtains a nice crisp. Serve with a garnish of your choice.
