Remove the silver skin from the ribs (see our first baby back ribs video https://senorpelon.com/baby-back-ribs/ )
Apply a generous amount of BrainRub to the meat side of the ribs.
Chill in the fridge 30+ minutes.
Place the ribs Meat Side Down on the smoker rack. This allows the fat on the ribs side to render into the meat instead of just dripping away.
Remove the ribs from the smoker and place into a wide shallow pan Meat Side UP.
Put equal parts Apple Cider Vinegar and Water into the pan to a depth of no more than 1/4 inch.
Cover with foil and steam in the oven an hour or more.
To test if ready: Pick up a rack of ribs with tongs to see if it gives easily.
Baste with LargoRado BBQ sauce.
Place Meat Side Down onto the grill to caramelize the sauce.
(You can also do this Meat Side Up uncovered in the oven on broil.)
