Tips
For those who keep Shabbat and holidays - the recipe should be prepared in advance as written in its entirety and heated on the hotplate for at least an hour before the meal, with the dish covered and not exposed.
The same recipe can be prepared with a lamb shank - note that if the weight of the cut is between 3 kg and 4 kg, the marinade, garlic, spices and rosemary should also be doubled and two more hours should be added in the oven (7 hours total, wrapped)
