Vegetable oil
Salt and pepper
3 pounds combined beef shank and oxtail pieces
2 onions, quartered
2 ribs celery, halved
2 carrots, halved
3 cloves garlic
1 bunch parsley
1 teaspoon black peppercorns
2 quarts water

Cooking Recipe:

Place pressure cooker over high heat. Oil and salt the oxtail and shank pieces then sear in batches. Add remaining ingredients and cover with water, being careful not to fill above the cookers "maximum fill" line. (If your pressure cooker does not have a water line, fill the pot 2/3 full). Bring to a boil and skim off any foam that gathers at the surface. Cover and lock lid. Once pressure builds up inside the cooker, reduce the heat so that you barely hear hissing from the pot. Cook for 50 minutes.

Release pressure using your cookers release device (read that manual) or cool the cooker by running cold water over the lid for 5 minutes. Carefully opening the lid and strain squeezing the solids before feeding to the compost pile, or the dogs. Strain through a fine sieve or several layers of cheesecloth. Season and serve or use as a base for other soup recipes.

Add the pasta and cook until tender, about 8 minutes. Remove from the heat and drain. Drizzle the pasta with olive oil. Season the pasta with salt and pepper. Using a box grater, grate the cheese. To serve, mound the pasta in the center of each bowl. Spoon the meat balls and sauce over the pasta. Garnish with the grated cheese.
