I normally make this in a large iron roasting pan. If you don’t have a large heavy pot that will hold at least 5 liters or 5 quarts, you can start this off in large heavy skillet and then transfer everything after you brown the meat to a larger ovem proof dish or stainless steel pot. It will need to be covered in the oven so the pot needs a lid or you need to have some aluminum foil handy.
Heat the oven to 250°C or 450°F. Place the bones in a small metal pan, coat them with vegetable or olive oil and brown for about 25 min. When brown remove from the oven and set aside.
As soon as you are done browning the bones reduce the oven to 180°C or 350°F
To begin cut up the bacon into smallish bits and fry until golden brown and then remove from the pan and set aside.
Begin to brown the meat that you have cut up into cubes about 3 x 3 cm or 1 ½ x 1 ½ inches. You want them large, they will shrink while cooking to about half that size. Brown the meat well over a high heat in the bacon fat that remained in the pot.
As you brown the first batch of meat sprinkle in the sugar and let it caramelize in the pot. This will help give the sauce a really beautiful color when finished. When the meat is nicely browned, remove the meat to a dish with the bacon.
Do not crowd the pot, brown only what will fit in one layer in the pot. If you are using something smaller to begin with brown the meat in batches. You might need to add a bit of olive oil to help stop the meat from sticking to the bottom of the roasting pan while browning.
Now add the butter to the empty pot, melt and then sprinkle in the flour. Mix it well with the butter, cook for a minute or two and add the hot liter or quart of veal or beef stock a little at a time whisking to insure that there will be no lumps. Be sure to scrape up everything that is stuck to the bottom of the pot – it will add huge amount of flavor to the finished dish.
Bring it to the boil on the stove and add the chopped tomatoes, wine, bouquet garni, garlic, and the dried thyme or rosemary if you are using that. Bring it back to a simmer and add the bacon and the browned meat and bones. There should be enough liquid to cover the meat.
Now if you are going to use a large oven dish or pot because you don’t have a roasting pan big enough to hold everything, do it now. Transfer everything to a heat proof oven dish or pot that has a lid. Aluminum foil will do fine if your dish has no lid.
Cover and place it in the lower third of a preheated oven set at 180°C or 350°F and let cook for one hour.
