Beef tenderloin with jack mackerels

In the book of Ukrainian author Olga Franko, we found two recipes following one another - one with fish, and another one with meat. One day during the experiment, our chief Ievhen created a new dish, combining these two recipes. There is a big worldwide trend of combining fish and meat on one plate. For example, everybody knows about one popular dish of Italian cuisine called Vitello Tonnato – veal and tuna, combined. Our dish is the Ukrainian version of such a combination of fish and meat, which is also called surf and turf.
