Ingredients:

6 pounds bone-in goat (or lamb) shank, with some ribs, bones cracked by the butcher at several places, but pieces still attached
2 pounds medium potatoes, peeled and quartered (optional)
fresh carob tree twigs or vine cuttings (for the clay pot)

For the marinade:
1/4 cup lemon juice
1/4 cup olive oil, more if you are baking potatoes
1/3 cup dry red wine
8 cloves garlic, peeled
2 tablespoons Greek oregano
2 teaspoons ground cumin
2 to 3 teaspoons pepper or red pepper flakes to taste
2 teaspoons salt or to taste

Method:
1. The night before baking, wash the meat, pat dry with paper towels and place in a deep pan that holds the pieces snug
2. In a blender pour the lemon, olive oil, wine, and add the garlic, oregano, cumin, pepper and salt, and process briefly. Pour the marinade over the meat, turn the pieces and rub to coat all over
3. Cover and refrigerate overnight, or up to one day
4. Preheat the oven to 475 F.
5. Line a large clay pot with carob tree twigs or vine cuttings and place the meat on them. Pour the marinade over the meat once more, cover with the lid and place in the hot oven. Bake for 20 minutes and reduce the heat to 300 F. Bake for 1 1/2 hours. Meanwhile, if you are using potatoes, warm 1/4 cup olive oil in a large skillet and sauté the potatoes, turning often with a spatula, just until they start to colour.
6. Remove the clay pot from the oven and place on a wooden surface or on folded kitchen towel. Uncover, lift the meat, discard the twigs and add the potatoes to the pan, tossing with the pan juices. Place the meat over the potatoes, cover, and continue baking for another 45 minutes to an hour–or more, until the meat and potatoes are cooked.
7. Uncover the pot and, if you like, bake for another 15 to 25 minutes, until the skin is charred and crackling–usually this step is not needed. Bring to the table, carve, and serve immediately.
