Pour in the white wine and add sugar and cinnamon.
Cover with the grated tomatoes and 1 liter of water. Cover the pot, lower the heat and let the meat braise for 1 hour.
Taste and add salt the pepper according to your prefernece.
In a frying pan, warm the remaining olive oil and saute the orzo over until it absorbs all the oil.
Preheat the oven to 170 degrees.
Transfer it to a pyrex pot, add the braised meat and pour over the sauce. It is essential that the sauce cover the orzo. If it has been evaporated during boiling, add some warm water (to fully cover the orzo).
