I don't call them 'burnt ends' , but I have done some cubed bacon , smoked up to something close to 190F internal temperature, with some sort of sweet sauce on them as sort of a glaze... Bacon Cubes I think is the term I'll use for them...
I've gotten pretty good a making some wings on pellet grill... at least my wife, daughter, and myself all like them. Basically I use my own modified version of Memphis dust, basically I substitute some Chipitole powder for at least half the paprika that's in the Memphis dust recipe. This gives it a little kick, but not super hot either ( depending on how much of the Chiptole powder is used ). I cook at like 325F for a hour in my pellet grill ( until internal temp is at least 175F or so ). So, I'm sure wings will be on my snack table...
