It's margarine. It's disgusting. It's not surprising to see at comps, just one of the several reasons I dislike so much of what is passed off as "flavor" of comp Q.
As it is mostly a cheap oil blend it won't "burn off". Certainly not at typical cooktemps.
The sugar simply melts into whatever - butter, clarified butter, another fat. Parkay not required. Very easy to just make a glaze ahead of time - do any necessary melting first - and apply at the end of cooking.
Clarified butter is a dream as are the wonderful flavored butters you can make - slices of rosemary butter on pork loin - to die for. That said, if the judges want margarine, either lose trying to convince them otherwise or go along to get along. Now that the different techniques have been discussed, time to figure out what you and your guests like best. "Disgusting" is a subjective term, not an inappropriate opinion on the board, but warning you can chose to heed or not. Not sure that adding butter or margarine to bbq meat really makes a difference as to whether or not it is "healthy" - another subjective term.
