I’ve heard these are the best way to go for wood. (heheheh). However, they aren’t cheap. Can you reuse them? Maybe if you soak in some booze for a bit?
I think they’ll give up most of their flavor in a few weeks. The best thing to do is to let them soak that long and then discard or use for smoking meat. YOu can break off pieces and not use the whole spiral at once.
