How to Marinate lamb shoulder
Put the cut lamb pieces into a large size roasting pan. Season it with salt and crushed peppers. Add chopped celery, carrots, and onion. Put in one cinnamon stick. Add some crushed or chopped garlic. Pour in a little vinegar to mask the cooking odor. Add a little white wine, but don't use cooking wine; in addition to tenderizing the meat, a good wine will add to the flavor. Toss in some sage leaves and rosemary needles (not the whole stalk). Toss the mixture, cover the pan with plastic wrap and let it sit and marinate in the refrigerator for 4 to 6 hours or overnight.
