why do you add DNB first and wait for others? Last time I mixed DNB and symphony there was this strange burnt taste instead of ash. Could this be related?
When I first started mixing a more experienced mixer than myself told me to add the DNB first and leave it for at least 24 hours before adding any other flavourings. I honestly cannot remember why. Although I still have DNB in my flavourings collection I can't remember the last time I used it. Sorry I can't be of more help.
