Put the seasoning ingredients into a blender to make a paste.
Rub on the rabbit pieces, and refrigerate overnight in a zip lock.
Preheat the oven to 350. Use a roasting pan or baking dish large enough to hold the rabbit pieces and onions and fennel.
Place fennel, onion, pancetta, garlic, and fennel seeds around and between the pieces, and put half the fennel leaves on top.
Sprinkle with olive oil, salt and pepper.
Roast 30 minutes.
Add wine, and roast for another hour.
Baste every 15 minutes with pan juices. If pan becomes too dry, add more wine or water.
Raise the heat to 450.
Cook 15 more minutes until rabbit becomes golden brown.
Turn rabbit pieces, and roast another 15 minutes, basting once more.
The fennel and onions should be tender and nicely browned.
Transfer rabbit and vegetables to a heated platter and keep warm in the oven while you make a sauce.
Set the roasting pan over burners on high heat, and de-glaze with the wine and stock.
Scrape any brown pieces from pan and boil down liquid to about half.
De-glaze for 3-5 minutes.
Sprinkle the remaining fennel leaves over rabbit as a garnish and serve sauce alongside rabbit.
