I really love lamb and braised meat in general, so this is a favorite. This slow-cooker meal is one I make for my family on Sundays. It's perfect because you can prep in the morning, spend time with the family and then have a finished meal waiting for you eight hours later.
Personally, I love anchovies. I know a lot of people are turned off by them, but they add great umami flavor. Don't worry -- you won't taste anything fishy in this dish!
Season shanks both sides with salt and pepper. Heat 2 tablespoons of olive oil in large saute pan, over medium high heat. Brown lamb shanks on all sides. Remove to separate plate.
In same pan, heat another 2 tablespoons of olive oil over medium heat. Add onion, carrot, and celery. Cook until soft, about 10 minutes. Add anchovy, garlic, peppercorns, tomato paste and cook for about 3-4 minutes. Then add wine, sugar and vinegar and bring to a boil. Cook for about 4 minutes to get rid of alcohol.
Add browned shanks to slow cooker, then add vegetable mixture on top. Place rosemary bundle inside. Pour in 5 cups of beef broth. Cook on low for 8 hours or high for 4 hours. If the liquid gets low during cooking, just add a little water. After the shanks are cooked, if the sauce is too thin for your taste, remove shanks and reduce sauce on stovetop.
While the shanks are cooking, make the couscous.
In large pot, bring 8 cups of water and 1 tablespoon of salt to boil. Add couscous and cook until tender, about 8 minutes, then drain
While couscous is cooking, make vinaigrette. In a bowl, mix the oil, honey, mustard, lemon zest and juice. Season with salt and pepper. Drain cooked couscous, and add to a large bowl. Pour dressing in and mix well. Then add fresh herbs, red peppers, raisins, pine nuts. Taste and add salt and pepper as needed. Enjoy warm or refrigerate and serve with lamb shanks.
