The alcohol is
not cooked off.. however the bigger concern seems to be the worry of buying a bottle of wine, using a splash for a recipe, and having wine in the house. There was no way I could do that in early recovery! I've loosened my 'food with alcohol' stance for myself a bit since then but I sure as hell wouldn't buy a bottle of alcohol to cook with.
I think we all need to figure this stuff out for ourselves.. while I have no issue eating penne alla vodka a few times a year, I sure as hell wouldn't drink an NA beer with much less alcohol content, it's a psychological thing for me.
It is good however to be aware of alcohol content in foods/drinks that you don't expect. Many people are trying to live completely alcohol free, and you wont get in any 'ut oh' trouble if you're aware
Glad you're doing well.
