Preheat oven to 325 degrees or prepare your BBQ/Smoker for your own preference.
Whisk together the dry rub ingredients.
Use 1/3 of the mixture on each slab of ribs that you have. Each slab should be approximately 3 lbs ( see the ones in our photos for size reference.) Place any remaining rub in a sealed container for later.;
Place the ribs on a lightly oiled baking sheet.
Bake in the oven at 325F for at least 2 1/2 hours, until the meat is pulling off of the bone.
Cook in the smoker or the BBQ according to your favourite methods, usually around 250 ° for 4-5 hours until the meat is falling off the bone!
PLEASE NOTE that the calories are calculated on the SPICE only and doesn't include any ribs that you are using!
You usually don't want to run your indoor oven long, which is why you can cook them at a higher temperature than the smoker or BBQ. You can also cook them lower and slower inside!
