This is pretty much the standard by which all others are judged. Smoke to about 160 and then wrap to 195. Something that I tried and got rave reviews was I injected with the Tony Chacheries garlic butter that I use for turkey's and it was unique and everybody complimented it. I mostly just cut my BBQ sauce with Apple cider vinegar so that it is thin enough to inject and use that. It gives me the flavor I'm ultimately going for anyway.Mix of apple juice, apple cider vinegar, and brown sugar for me. Sometimes I put in the rub I am using as well.
I know it is too late but, I do not inject. I like to baste my butts. I use a water and apple cider vinegar base for my baste and add my rub to it and bring to a boil. I cook it low and slow basting every hour or so till it gets to 165-175 then sometimes I rap it with foil and sometimes I don't. Wrapping it just speeds up the cooking process to me. When I wrap it, it seems to make the bark soft, sometimes I like that sometimes I dont. I will cook till it gets to at least 200 if I am going to pull it. I like the natural taste of the fat in the pork, I do not like to cover it with an injection. That is how I like it but as they say different strokes for different folks. Also, I use no sugar because it seems to give a burnt taste to me, I use a heavy salt and pepper blend. When you mix that wonderful bark in with the rest of the pulled meat it really incorporates the flavor throughout.
I need to try injecting one as well. I normally rub the outside with olive oil (not much, just enough for the rub to stick) then use either a homemade rub or Dizzy Pig Dizzy Dust. I also put it in a vacuum sealed bag and let it sit in the fridge overnight prior to smoking.
For those that inject with apple juice, cider vinegar, etc., what measurements do use for each?
