Preheat your grill to 300 F, over indirect heat. 

Pat the ribs dry, then evenly apply the Dijon mustard and Sunshine State of Mind BBQ rub.

Place the ribs on the grill and cook for 2 hours.

Lay down a large piece of foil, line the pats of butter down the center followed by the rub and sugar. Then, place the ribs non membrane side down.

Return to the grill for 30 minutes or until the rack of ribs bends with ease.

Uncover and allow them to cool slightly.

Slice the individual ribs all the way against the bone of the next rib to have a nice meaty bite per rib. 

Garnish with more pepper flakes, sesame seeds, or thinly sliced green onion if desired.
