I agree with the parent comment and I also agree with you. The reason is that I believe that the states rule mostly applies to permanent things (i.e curtains or mugs) while you are commenting about a consumable. Everyone likes when you bring olive oil from vacation and, if it meets a certain minimum, everyone likes when you bring cake. In your case, you further have the DIY aspect. DIY things are generally interesting (though it depends on the quality of the item and the relationship between giver and receiver). But store bought stuff that the receiver may as well have bought themselves? If I am invited to a (non-BYO) BBQ, I would never bring a potato salat from the local supermarket. But I would (at times) definitely bring a home made one.
