Baking choc nibs? Would that be like chocolate chips? Nibs most people use in beer are crushed dried beans.
That said, I’ve used nibs a few times. Last was in a big 13% Imperial stout, so I used quite a bit.
@EzyLee Coconut can be a nice addition, but I personally havent used it. IIRC, it doesnt take loads of toasted coconut to add some smooth nutty/vanilla-y notes.
