This was a delicious sauce. I used only one pound of meat - wild boar, but kept the other ingredients the same (except a little more of the veggies) to serve 4 people. We were happy with the ratio, and thought there would not have been enough liquid had we used 3 pounds of meat. The long cooking time gives this ragu a lot of depth. I added the bay leaf in step 3 (it is missing from the instructions) and kept the sauce covered on the stove, since I assumed that was the intention.
Excellent bolognese sauce. Used bacon instead of prosciutto (I had it on hand) but followed the rest of the recipe faithfully. Had a wonderful, rich flavour. A keeper.
