That sounds like a lovely trip. We have done similar trips in the past, but usually fly into Germany, as that is where my husband's relatives live. It has been awhile since our last trip, and I don't remember any restrictions, though there might have been some. It is a long flight from CA or, in our case, OR, so most likely whatever I took with me was eaten before arrival. That would still be my best advice to you; take what you need for the flight, and either put any leftovers in the trash on the plane when you arrive, or take your chances with Customs. Be honest, tell them what you have, and they might let you keep it. Europe is a wonderful place to stock up on snack type foods - forget the bakeries, and head for the butcher (sausage, cold cuts) and cheese shop!
That sounds very strange about the woman being fined. I wonder if that wasn't either a misunderstanding or a misreporting. The worst that should have happened, IMO and in my experience, is confiscation.
