Season meat with salt and pepper on all sides. Place meat in a big bowl with wine, thyme, bay leaves, carrots, orange, onion, and garlic. Cover and marinate in the fridge for at least 12 hours, and preferably 24 hours. Heat some olive oil over medium heat in a large stockpot. Remove the meat from the marinade and brown the pieces in the oil on all sides. Pour the marinade (including the oranges, bay leaves, etc.) over the meat and bring to a boil. Boil for 5 minutes, skimming any foam from the surface. Lower the heat to a simmer, stir in the tomato paste, and add 4 1/2 c. water. Cover, and let stew on low heat for 2-3 hours, stirring occasionally. 15 minutes before the stew is ready, add the pitted olives. Let cook for 15 minutes on medium heat without the lid to thicken the stew. Serve over mashed potatoes, rice, or pasta. Garlic Mashed Potatoes Place cubed potatoes in a large saucepan. Cover with cold water, salt liberally, and bring to a boil over medium heat. Boil for 10-15 minutes until potatoes are easily pierced with a fork, skimming starch foam from top occasionally and checking to keep from boiling over – lower heat if necessary. Drain potatoes and place in a blender. Return saucepan to heat, lower heat to low, and add garlic and heavy cream. Heat until garlic is fragrant and cream begins to simmer, then add to blender. Blend until potatoes are a totally smooth puree. Add water or skim milk as necessary to even out texture.
