Remove any excess fat from pork ribs, then brown ribs lightly in olive oil. Set aside on plate.
Place carrots and potatoes in microwave-safe dish, add water to cover, microwave for about 4 minutes on high. Drain off water.
Make a layer of onions, potato slices (these can also be placed around the inside of the crockpot) and carrots, place a pork rib on top. Sprinkle some of the garlic and spices on meat, then repeat process until crockpot is filled. Pour apple cider vinegar over everything, put the lid on, fire up the crockpot, and simmer everything on low for at least 8 hours. If you like, sprinkle a little brown sugar in there, too. This is the sort of recipe that lends itself to being inventive. Enjoy.
