I just heard an account from someone who studied in the Soviet Union in the late 1950's, early 1960's. She said when she was served given a glass with a raw egg in it, and then very hot black tea was added. Then, a pat of butter was put on top.
Is this true? Is this something common now? What is it called?
She said she was sick at the time. Is this something only for sick people?
It sounds tasty to me; I want to know how to prepare it properly, and the correct occasion for drinking it.
Edit: I just got a clarification, she was studying in the Ukraine SSR, not Russian SSR. I have edited the title to fix it.
