If I thought like your friend, I haven't been sober these last 6 months. Geeze! Agree with others that I don't cook with wine. But I think probably everything has trace amounts of some kind of alcohol. I live on balsamic vinegar and oil on salads as it's healthier than bottled stuff. Just go with your gut. Everybody's journey is different. As long as you are not chugging bottles of balsamic and bbq sauce, I'm sure you're fine.
