Lay out 2 long pieces of heavy duty aluminum foil on top of each other on the counter, long enough to double wrap the rack of ribs front and back with the two pieces. Repeat with the other rack.
Spread ½ cup of brown sugar on each set of aluminum foil, then drizzle some honey, parkay squeeze butter, and Tiger Sauce on each. (this is optional)
1 Cup Dark Brown Sugar, 2 drizzles Honey, 2 drizzles Parkay Squeeze butter, 2 drizzles Tiger Sauce
Once the ribs are a nice dark amber color and especially if you begin to see any very dark burning on the bones or ends, usually around the 2.5 hour mark, remove them from the grill using tongs or heat resistant gloves.
Place the baby back ribs face down into each pile of aluminum foil and ingredients.
If you would rather not use the wrapping ingredients listed above, place the ribs in the foil face up and add a small amount of apple juice, soda, or beer to the aluminum foil to add some moisture.
Wrap the ribs tightly in the double layer of aluminum foil and place back on the Pit Boss and continue to cook at 250°F.
