overseas fishes

A man, reporting his trip in Hungary, told me about poor people's way of cooking fish in gourmet style: they flay (I don't know what kind of) fish, mix its flesh up with egg and vegetables, put this filling again in the skin, and slice it like a salami.
This man also told me about a fish they often cook in that region: it's called lucioperca, and, when baked, it incurvates like an ark.

Another overweight man told me about his trip: he went in Benin for work, in a hinterland zone, far away from the sea and whatever water source, but during a work dinner they served just one dish: fishes' heads. Everybody there was so satisfied and kept ravening the head, but he couldn't even touch it. Bwleah.
