Okay. So booze infused eggnog isn't going to do for you. There is a
non-alcoholic rum alternative you can use in eggnog and to make "rum" soaked pastries.
Aside:
I fully believe you've not ever drunk alcohol, but if you've eaten pastries, especially homemade one's like cakes and cookies, you've had alcohol, but like most folks, you didn't realize it. Most "regular" cakes and many a cookie are made with
vanilla extract (or some other extract) and guess what's in that? Alcohol -- 35% (aka 70 proof). And, no,
all the alcohol didn't cook out in the process of baking the cake. Some other relatively common dishes that will have alcohol, usually wine or cooking sherry, in them are gravies and sauces, and risottos. I don't know how much fine dining you do. If you do much at all, you definitely encountered a sauce with wine/sherry in it, regardless of whether it was indicated on the menu.
I get that none of that is like drinking booze, which is most certainly what rum, etc. in eggnog is and, if one eats enough, it's effectively what eating alcohol soaked cakes is too. I'm not trying to "upset your apple cart" or convince you to drink hootch. I'm just saying that you may want to disabuse yourself of the notion that you've "never had a drop of alcohol."
