To finish:
In a medium sized sauté pan heat the olive oil before adding the pancetta, it should sizzle gently when entering the pan. Cook it for 5 minutes before adding the grated vegetables, stir all together well.
Add the spices and the bay leaf, then cook for a further 5 minutes before adding the rabbit with the tomato purée. Stir altogether for a few minutes before adding the remaining ingredients.
Put a lid on the pan and simmer very gently for an hour. Note: Adding Parmesan rind will give the Ragu extra depth of flavour, but remove the rind before serving. Drop the penne pasta into boiling salted water and cook to your preference.
Drain and mix the penne through the Ragu, divide over 4 plates, adding a good grate of fresh Parmesan should you require it.
