I'm not a Chef, but I did do a lot of bartending during my first couple of years in sobriety. I've got friends who are sober that own liquor stores. I've got friends who are sober and they tend bar and work in liquor stores. We seem to agree on one thing... we as alcoholics can not attempt any taste tests... let alone have a drink.
Most of the A.A.'s that knew that I was tending bar thought I was nuts. They were probably right.
I stayed sober but I did quit tending bar.
Would I do it again? Maybe. Maybe not. I would definitely talk to my sponsor about it, first... before I did it.
There is plenty of good advice in the Big Book, for questions like this. I've found that some good advice to myself has been... if in doubt... don't.
You mention that you have long term solid sobriety. That would seem to have different meanings for different folks.
I'm in frequent contact with alcoholics who had long term solid sobriety before their last spree.
Hopefully, I'll never have to ask them to sponsor me.
Good luck with your decision and the possible new career choice!
