Lightly oil the grill rack and grill the "T" Bones, turning over once, until cooked to desired doneness, approximately 6 to 9 minutes. Season with salt, pepper and cumin. Baste with pork stock. Transfer to a clean platter and let stand for 5 minutes. Serve with Grapefruit Emulsion, Roasted Beets, and Fennel Mashed Potatoes.
Remove the bones from the roasting pan, discard the grease, and deglaze with the wine. Combine all ingredients in large stock pot except for salt and pepper. Skim the impurities from the top of the stock, as needed. Cook at a simmer for 6 to 8 hours. Strain and reduce to desired thickness. Season with salt and pepper.
Place the beets, 1 tablespoon olive oil, 1/4 teaspoon salt, and 1/8 teaspoon pepper in a roasting pan and cook until the beets are tender, about 40 minutes. When they are cool enough to handle, remove the skins and slice the beets.
Place the beets in a small pot; reheat with the remaining olive oil, orange juice, cardamom, 1/4 teaspoon salt and 1/8 teaspoon pepper.
Place the potatoes in a large saucepan. Cover with cold water and bring to boil. Reduce heat to medium and boil until potatoes are tender, about 15 minutes. Drain. Return potatoes to pan; cook over medium heat until no liquid remains. Mash potatoes.
Add fennel mixture and butter to potatoes and mix until creamy. Season with salt and pepper. Add spinach puree just before serving, adding color to the dish but not to overpower the fennel.
