Would you serve a wine based sauce to your kids? If so, then go for it.
FWIW, I did a back of the envelope calculation for beer battered fish.
For four pieces of fish, 300 ml of lager was required. Assume that 2/3 of the beer is actually deposited on the fish, and 1/2 the alcohol cooks off in the frying process. That leaves 25 ml of beer per serving.
If you take a standard lager as 5% alcohol, then the alcohol consumed by the child is only 20% of the amount of alcohol in a single dose of Nyquil cough syrup for a 12 year old.
depends on whether they're *your* kids ;) actually i'm not totally joking...most, but NOT all of the alcohol will cook out, so it really depends on how much beer you're adding, and how comfortable you (or the kids' parents) are with the idea.
when this topic comes up there are always people who jump in to say that a *tiny* bit of alcohol won't kill anyone, but it is important to consider extenuating circumstances...like if there's alcoholism in the family and the parents want to avoid exposing the child at all costs.
