Probably too late but what the hell. I do Crock Pot Carnitas. I don't measure so please forgive:
Beer
2 Jalapeños
1 onion sliced
cumin
adobo
chipolte powder
1 bay leaf
1 bunch of cilantro chopped
I throw it all in the Crock Pot and set her on low for 8 - 12 hours. Pull just like you would pulled pork, I mix some of the Crock Pot juices into the pulled meat, salt/pepper to taste, lay out on baking sheet and put in oven just long enough to crisp-up the top layer of the meat.
Serve with warm tortillas, white onion, cilantro, guacamole or sour cream, diced tomatoes and ice cold Mexican beer.
Great on a cold winter afternoon.
