Preheat oven to 350 degrees F.
Rub ribs with 1 cup Big Daddy Rub until evenly coated on both sides. Allow ribs to marinate at room temperature for 30 minutes.
Place ribs in 2 large roasting pans and cover with the cola and water. Cover with foil and cook in oven for 1 1/2 hours. Remove ribs from oven and allow to cool. Slice ribs into individual-size pieces.
Preheat grill over medium-high heat.
Place ribs on the grill. Brush on apple cider-buttermilk sauce. Cook for additional 5 minutes.
In a large bowl, toss ribs with another 1 cup of rub until well coated. Spread ribs out on a sheet tray and bake in the oven for an additional 20 minutes until caramelized.
Serve alongside Apple Cider Buttermilk Sauce, chipotle aioli, or harissa rouille.
In a medium sized bowl, mix all ingredients until well combined.
