*** I accidentally omitted the cider vinegar when I filmed the video, but I usually put 2-3 tablespoon in the apple butter bbq sauce. This bbq sauce was delicious in the video, so I have switched that ingredient to optional. The only difference between the two is the cider vinegar does make it a little snappier with a touch of tart. Use your judgement and you can always add the vinegar after cooking to see which you like better.
