First, you need to prep the sauce. Choose your favorite bbq sauce, I suggest one that is an original flavor without a bunch of added flavors such as honey, chipotle, sweet sour and so on.
In a pot add the bbq sauce and a can of Dr Pepper. Turn your stove on a medium heat to bring the temperature up slowly to a boil. If you boil too fast the acid in the soda will cause the pot to boil over. Cook the sauce until the foam disappears. This will take about 5 minutes after it starts boiling.
Remove the ribs from the package and season with coarse salt and pepper.
Then, add the ribs into the crockpot and pour 1 cup of the cooked bbq sauce into the crockpot. Cook on high for 4 hours or low for 6-8 hours. Check the ribs for tenderness that's when you know you're done.
To finish the ribs, add them into a baking dish and cover them with the leftover bbq sauce and bake in a preheated 400F oven for about 15 minutes to thicken the sauce around the ribs. This is optional, it helps the sauce stick.
Lastly, allow the ribs to cool a bit then serve.
