Wash the rib and cut ribs to desired size.
Use your pinky to slip through and pull out membrane if needed, otherwise, just pierce with a fork if you want more crunch, tendon-like texture.
In a clean and dry container, combine all the dry rubbing ingredients.
Rub them good onto each side of each slab, crevice and all.
Save the extra dry rub to mix with your sauce if desired.
Preheat oven to 400 F.
Arrange rubbed ribs onto baking sheet and bake for 20 minutes with turning in between to sear all the meat and seal in flavor. This should remove some extra fat as well.
Once your ribs are all seared, remove from oven, and arrange into your slow cooker.
Arrange each rubbed and seasoned slab into your slow cooker.
Pour 2 cups of sauce (store bought or make per instruction below) all over the ribs.
Cook on low for 8 hours or high for 4 hours.
