When you cook or bake with alcohol the majority, if not all of, the alcohol itself is cooked and/or baked out of the actual product you are making. What's left is usually a hint of the taste of the alcoholic beverage. That's why when you make.. say, rum cake, for example, you have to add rum to the cake after you've baked it even though there's rum included in the batter itself.

Still, I know that there are people out there who won't or can't eat anything made with alcohol in it for various reasons. I myself am an infrequent and rare drinker of alcohol at best. I might have a single drink in a year.
