Why should you not use Karo with vanillin??

[Hockeyhunter99]

Maybe i am spelling this wrong. i have a recipe for a beer that calls for corn syrup (Karo). been looking around and have found that it is not a good idea because of the vanillin that is in the ingredients. people on here say not to use the Karo with vanillin but i can't seem to find out why.

anybody know.

thanks in advance

Flavor. Unless you're making something that should have vanilla flavoring in it, you probably don't want vanilla.
