Smoking a couple butts today, I've done about 3 in the past and always have the same problem, great flavor great smoke but the bark never gets to hard or carmalized, it always seems to be a bit mushy, is it from too much rub maybe? Or I always put mustard on before the rub? But never had any problems with the rub on my ribs being mushy?? Here's some pics of the butts today.
