i have a Masterbuilt XL propane smoker. my Question is when i smoke my ribs the top and the side of the rib looks great but the under side is Black , the ribs taste great but the black is a little off setting .
i have tried a pan on the rack below the ribs both empty and with water but still the same , like i said the ribs are great tasting and fall off the bone which the wife loves but not sure why the ribs are so black on the under side .
i cook them at 240 degrees for 4 hours i do not turn and do not foil them .
i have 3 therms added to the smoker and all three are with-in 10 degrees.
