I got this recipe from the blog "A Year of Crockpotting" and they were delicious!! A friend of mine tried them too (since our local grocery was having a buy one get one free deal on ribs) and have rave reviews as well! It is John McCain's recipe.
4lbs of ribs (I used baby-back)
1 T kosher salt
1 T pepper
1 T garlic powder
Mix dry ingredients and rub over meat. Squeeze the juice from 4 lemons over the top. Cook on low 8-10 hours in the crockpot.
These were super simple and the meat fell off the bones...very yummy. I'm excited to eat the leftovers tonight!
