This was awesome - such depth of flavors! I, too, refrigerated the meat with the spices for about 20 hours, then threw everything into the crockpot. Cooked on low 10 hours, then 'keep warm' for about 2 hours. Made for ZWT9.
This was OUTSTANDING! The best part is, I made it all in the crockpot! I marinated the lamb with all of those delicious spices for 24 hours. The next day, I just threw the meat, onion, and carrots in the slow cooker as well as a "sauce" of 1/2 can chicken broth with the ginger, garlic, tomato paste and honey. I only used 1/2 can of chicken broth as crockpot cooking creates more liquid. The aroma throughout my home was to die for. I cooked the tagine for about 8 hours on low and served it with couscous. The spices really do make this dish. I'm going to mix up some more and try using it as a rub on chicken next time. Thanks so much for posting, I really enjoyed this! :)
