This dish from an ordinary river trout I have called so strange in honor of my daughter and my son-in-law who live in the German city of Erlangen. For this recipe they cooked mackerel. I thought: what kind of mackerel it is better for our trout? Turned out surprisingly delicious! Hopefully not worse than the mackerel. However, in addition to the main party cooking show – fish – I changed some other components. Instead of rosemary used dill and Gorgonzola was replaced by Dor blue – it is unknown what country of origin. Parmesan Parmesan cheese remains, although acquired Lithuanian accent. But the result is important, right? It has been achieved.
