@ BBQ Bubba, that is exactly how I pipe the filling into "Deviled Eggs". Kind of a disposable mixing/piping bag.
As for ABTs I like the split in half method. I tend to mound the cheese mix kind of on the proud side and then put the stuffed peppers into the fridge for awhile before wrapping with bacon. This lets the cheese firm up a bit and makes the bacon wrapping a little easier.
As for freezing? I don't know. Maybe in their unsmoked state, to have on hand for the next time that you smoked. Freezing in my opinion degrades everything just a bit and some things more. I don't think that I would freeze precooked ABTs and expect the reheat/thaw to be very kind to them. (Ain't no smokked ABTs gonna be left overs either, it's just one of those things)
ABTs are indeed a thing of love, they are alot of work for what they are. Spend almost an hour making them and then maybe two hours in the smoker, ten bucks or so in bacon, cheese and peppers. And for what? Out of two dozen I am lucky to get six! (Actually I knew the sacrafice when I took them into work the other day, if you want to be a hero, take some to the crew!)
I did a couple of "Anahimn" (SP) bannana peppers in the last batch, they were pretty good too. I just wish that I could tell what the heat will be on the Jalapenos, they were all over the place, from under ripe green to mild (NO Complaints here!) all of the way to "Damn! I can't believe I ate that!" hot!
Evryone that tried any has asked what I would charge for a batch of a dozen or two. I think that I could name my price, but I just don't want to have to work that hard for money!
