The documentary was a German production "Von Gorodez bis St. Petersburg" They went from the Black Sea to the Baltic Sea, showed a lot of interesting sights along the way and interviewed the people they met.
I grew up in cold war Europe, but even in our so called western world, we always had Russian friends. My grandfather was a brilliant chess player and he was in contact (by written letter !) with people from all over the world. His best friend was Russian and I remember him as one of the friendliest men I ever met.
We enjoyed a few extraordinary meals, although I wouldn't be able to name the dishes. Actually, my wife wants to do "Russian weeks" in her café and we could use a few good ideas for breakfast..
I'll look for that documentary, it sounds very interesting. Russian breakfast is a wonderful idea 👏🏼 There are so many options!! I'll put something together for you and your wife 🍴
