Question: do i wrap ribs in foil?
Answer: Remove ribs from the smoker and wrap tightly in aluminum foil to form an airtight seal. Return to the smoker bone-side up and smoke for two hours. Unwrap the ribs and return to the smoker bone-side down for one more hour. Apply sauce to ribs (if you want) during the last 20 to 30 minutes of the cooking time.
