So, here's the result. Cut end off after 7 hours - we were hungry! - and put rest back on spit. This is after 10 hours.
Not much of a smoke ring but it tastes great.
Easy to pull with forks.
To be eaten tonight as pulled pork sandwiches on Cheese and Wholegrain mustard bread
Any observations / critiques?
Mine are:
-Pleased with first attempt
-Couldn't have done it without your advice - thanks all
-Gas Outdoorchef Ascona probably shouldn't be used for smoking unless only a light smoking is wanted? Would you agree?
-Probably should have tried something simpler to start
